Q12. Write a function modilst(L) that accepts a list of numbers as argument and increases the value of the elements by 10 if the elements are divisible by 5. Also write a proper call statement for the function.

For example:

If list L contains [3,5,10,12,15]

Then the modilist() should make the list L as [3,15,20,12,25]

Ans:

def modilst(L):

for i in range(len(L)):

if L[i] % 5 == 0:

L[i]+=10

L = [12,10,15,20,25]

modilst(L)

print(L)

Q13. Write a function lenFOURword(L), where L is the list of elements (list of words) passed as argument to the function. The function returns another list named ‘indexList’ that stores the indices of all four lettered word

of L.

For example:

If L contains [“DINESH”, “RAMESH”, “AMAN”, “SURESH”, “KARN”]

The indexList will have [2, 4]

Ans:

def lenFOURword(L):

indexList=[]

for i in range(len(L)):

if len(L[i])==4:

indexList.append(i)

return indexList

L=["DINESH", "RAMESH", "AMAN", "SURESH", "KARN"]

print(lenFOURword(L))

Q14. Write a python function displaywords() that will print all the words that are having length greater than 3.

Example:

For the fie content:

A man always wants to strive higher in his life. He wants to be perfect.

The output after executing displayword() will be:

Always wants strive higher life wants perfect

Ans:

strings='A man always wants to strive higher in his life. He wants to be perfect.'

def displayword(strings):

words=strings.split()

for i in words:

if len(i)>3:

print(i,end=' ')

Q16. Ravi a python programmer is working on a project, for some requirement, he has to define a function with

name CalculateInterest(), he defined it as:

def CalculateInterest (Principal, Rate=.06,Time): # code

But this code is not working, Can you help Ravi to identify the error in the above function and what is the solution.

Ans:

In the function CalculateInterest (Principal, Rate=.06,Time) parameters should be default parameters from right to left hence either Time should be provided with some default value or default value of rate should removed.

Q17. What do you understand the default argument in function? Which function parameter must be given default argument if it is used? Give example of function header to illustrate default argument.

Ans:

Default argument in function- value provided in the formal arguments in the definition header of a function is called as default argument in function. They should always be from right side argument to the left in sequence. For example:

def func( a, b=2, c=5): # definition of function func( )

Q18. Write a function INDEX_LIST(L), where L is the list of elements passed as argument to the function. The function returns another list named ‘indexList’ that stores the indices of all Non-Zero Elements of L.

For example:

If L contains [12,4,0,11,0,56]

The indexList will have - [0,1,3,5]

Ans:

def INDEX_LIST(L):

indexList = [ ]

for i in range(0,len(L)):

if (L[i]%2 == 0):

indexList.append(i)

return indexList

L =[12,4,15,11,9,56]

print(INDEX_LIST(L))

Q19. Write a function LeftShift(Numlist, n) in Python, which accepts a list Numlist of numbers and n is a numeric value by which all elements of the list are shifted to left.

Sample input data of the list

Numlist = [10, 20, 30, 40, 50, 60, 70], n=2

Output

Numlist = [30, 40, 50, 60, 70, 10, 20]

Ans:

def LeftShift(Numlist,n):

NumList=Numlist[n:]+Numlist[:n]

return NumList

Numlist = [10, 20, 30, 40, 50, 60, 70]

n=2

print("Original List",Numlist)

print("After Shift List :",LeftShift(Numlist,n))

Q20. Write a function SQUARE_LIST(L), where L is the list of elements passed as argument to the function. The function returns another list named ‘SList’ that stores the Squares of all Non-Zero Elements of L.

For example:

If L contains [9,4,0,11,0,6,0]

The SList will have-[81,14,121,36]

Ans:

def SQUARE_LIST(L):

SList=[]

for i in L:

if i!= 0:

SList.append(i*i)

return SList

L=[9,4,0,11,0,6,0]

print(SQUARE_LIST(L))

Q21. Write a function in Python Convert() to replaces elements having even values with its half and elements having odd values with twice its value in a list.

eg: if the list contains 3,4,5,16,9 then rearranged list as 6,2,10,8, 18

Ans:

def Convert(L):

SList=[]

for i in L:

if i%2== 0:

SList.append(i//2)

else:

SList.append(i*2)

return SList

L=[3,4,5,16,9]

print(Convert(L))

Q22. Write a function AdjustList(L), where L is a list of integers. The function should reverse the contents of the list without slicing the list and without using any second list.

Example: If the list initially contains 2, 15, 3, 14, 7, 9, 19, 6, 1, 10,

then after reversal the list should contain 10, 1, 6, 19, 9, 7, 14, 3, 15, 2

Ans:

def AdjustList(lst):

print("Reversed List : ",end="")

print(list(reversed(lst)))

lst=[2, 15, 3, 14, 7, 9, 19, 6, 1, 10]

print("Original list : ",lst)

AdjustList(lst)

Q23. Write a function EVEN_LIST(L), where L is the list of elements passed as argument to the function.

The function returns another list named ‘evenList’ that stores the indices of all even numbers of L.

For example:

If L contains [12,4,3,11,13,56]

The evenList will have - [12,4,5]

Ans:

def EVEN_LIST(L):

evenList=[]

for i in L:

if i%2==0:

evenList.append(i)

return(evenList)

L=[12,4,3,11,13,56]

print("Original List : ", L)

L2=EVEN_LIST(L)

print("Even List : ",L2)

Q24. Write definition of a method/function DoubletheOdd( ) to add and display twice of odd values from the list of Nums.

For example :

If the Nums contains [25,24,35,20,32,41]

The function should display

Twice of Odd Sum: 202

Ans:

def DoubletheOdd(Nums):

s=0

for i in Nums :

if i%2!=0:

s+=i*2

print("Twice of Odd Sum : ",s)

Nums=[25,24,35,20,32,41]

print("Original List ", Nums)

DoubletheOdd(Nums)

Q25. Write a function in python named SwapHalfList(Array), which accepts a list Array of numbers and swaps the elements of 1st Half of the list with the 2nd Half of the list, ONLY if the sum of 1st Half is greater than 2nd Half of the list.

Sample Input Data of the list

Array= [ 100, 200, 300, 40, 50, 60],

Output Array = [40, 50, 60, 100, 200, 300]

def SwapHalfList(Array):

s1=s2=0

L=len(Array)

for i in range(0,L//2):

s1+=Array[i]

for i in range(L//2, L):

s2+=Array[i]

if s1>s2:

for i in range(0,L//2):

Array[i],Array[i+L//2]=Array[i+L//2],Array[i]

L=[ 100, 200, 300, 40, 50, 60]

SwapHalfList(L)

print(L)

Q26. Write a function INDEX_LIST(L), where L is the list of elements passed as argument to the function. The function returns another list named ‘indexList’ that stores the indices of all Elements of L which has a even unit place digit.

For example:

If L contains [12,4,15,11,9,56]

The indexList will have - [0,1,5]

Ans:

def Index_List(L):

index_List=[]

for i in range(len(L)):

if L[i]%2==0:

index_List.append(i)

return index_List

L=[12,4,15,11,9,56]

print(L)

idx=Index_List(L)

print(idx)

Q27. Write definition of a method/function AddOdd(VALUES) to display sum of odd values from the

list of VALUES.

Ans:

def AddOdd(Values):

n=len(Values)

s=0

for i in Values:

if (i%2!=0):

s=s+i

print(s)

Values=[10,3,24,5,7,9,40]

AddOdd(Values)

Q28. Write the definition of a function Sum3(L) in Python, which accepts a list L of integers and displays the sum of all such integers from the list L which end with the digit 3.

For example, if the list L is passed

[ 123, 10, 13, 15, 23]

then the function should display the sum of 123, 13, 23, i.e. 159 as follows :

Sum of integers ending with digit 3 = 159

Ans:

def sum3(L):

s=0

for i in L:

if i%10==3:

s=s+i

return s

L=[123, 10, 13, 15, 23]

print(sum3(L))

Q29. Write a function Accept() which is accept the employee id from the user and display its detail from the dictionary. Data is stored in the dictionary in the following format

{Empid1 : (Empname1, EmpSalary), Empid1 : (Empname1, EmpSalary),…..}

Ans:

def accept(pid):

l=[ ]

if pid in emp:

l=emp[pid]

print("Employee id, Employee Name", "\t""Salary")

print(pid,"\t\t",l[0],"\t\t",l[1])

else:

print("Record not found")

emp={1:("Jyoti",25000),2:("Anshu",30000),3:("Dhairy",36000)}

print(emp)

pid=int(input("Enter the product id : "))

accept(pid)

Q30. Write a program to accept the employee id from the user and check Salary. If salary is less than 25000 then increase the salary by Rs1000. Data is stored in the dictionary in the following format.
{Empid : (Empname, EmpSalary}
Q31. Write a program to count the frequency of each character in a given string accepted from the user using dictionary.(Store the character as key and it’s frequency as value)

Ans

def accept(pid):

l=[ ]

if pid in emp:

l=emp[pid]

if l[1]>25000:

emp[pid]=(l[0],l[1]+1000)

print(emp)

emp={1:("Amit",25000),2:("Vanshi",30000),3:("Ravi",36000)}

print(emp)

pid=int(input("Enter the product id : "))

accept(pid)

Ans:

def freqDict(str1):

d={ }

for i in str1:

if i not in d:

d[i]=str1.count(i)

return d

str1=input("Enter any String")

dic=freqDict(str1)

print(dic)
