Python Tutorial: Find Syntax error(s)

1) Rewrite the following python code after removing any/ all syntactical errors with each correction underlined:

(a) def guess()

print("Hello")

print(a)

a=5

var=2

guess

(b) def add:

total=0

n=input("Enter a number:

m=input("Enter another number: ")

total=m+n

print total

add()

(c) def func(a+b):

tot= a+b

print(tot)

m=10

n=20

fun(m,p)

(d) def f1(b):

if b>0 then:

return “Positive”

else return "Not Positive"

m=int(input("Enter an number: "))

msg=f1()

print(msg)

(e) def isMultiple (a,b):

if a%b= 0:

return true

else return false

m=int(input("Enter first number: "))

n=int(input("Enter second number: "))

if isMultiple[m,n]:

print("m is a multiple of n")

else print(m, "is not a multiple of n")

(f) find HCF (a, b):

h=a

while b%h!=0 OR a%h!=0:

h-=1

return h

m=int(input("Enter first number: "))

n=int(input("Enter second number: ))

HCF (m.n)=h

print("HCF=",h)

Ans

(a) def guess(): #error 1

print("Hello")

a=5 #error 2

print(a) #error 3

var=23

guess() #error 4

(b) def add(): #error 1

total=0

n=input("Enter a number:") #error 2

m=input("Enter another number: ") #error 3

total=m+n

print(total) #error 4

add()

tot= a+b

print(tot)

m=10

n=20

func(m,n) #error 3,4

(d) def f1(b): #error 1

if b>0: #error 2

return "Positive"

else: #error 3

return "Not Positive"

m=int(input("Enter an number: "))

msg=f1(m) #error 4

print(msg)

(e) def isMultiple (a,b): #error 1

if a%b== 0: #error 2

return True error 3

else:

return False error 4

m=int(input("Enter first number: "))

n=int(input("Enter second number: "))

if isMultiple(m,n): error 5

print("m is a multiple of n")

else:

print(m, "is not a multiple of n") #error 6

h=a

while b%h!=0 or a%h!=0: #error 2, 3

h-=1

return h

m=int(input("Enter first number: "))

return display(string)

return n

def display (string):

return string==str(5)

print(show(“Children’s Day”))

print (display (string=’true’):)

print (show (5, “Good”))

Ans:

def show(n, string= "Good", k=5):

return display(string)

return n #Cannot return 2 values

return string==str(5) # indentation

print(show("Children’s Day"))

print (display (string="true")) # : to be removed

print (show (5, "Good"))

3. Rewrite the following python code after removing any/all syntactical errors with each correction underlined:

lst1=eval (input("Enter the list"))

displaylist()

Ans:

def displaylist (lst): # error 1

print("Even Elements of the list")

for i in range (0, len(lst)): # error 2

if lst[i]%2==0:

print (lst[i])

lst1=eval(input("Enter the list"))

displaylist(lst1)

4. Rewrite the following code in python after removing all syntax error(s). Underline each correction done in the code.
