Why error invalid literal for base 10 coming out for the code below, when character string is given as input?

Question

def tulis():
try:
print("u typed ",Inser)
except:
print("u have typed character string,instead of integer")

print("type a number")
Inser = int(input())
tulis()

Answer 1

You need to put the statement...

Inser = int(input())

... in the try-except block. This is because, if a non-number is entered, it can't change it into an integer. I suggest you do something like the following:

def tulis():
print("u typed ",Inser)

print("type a number")
try:
Inser = int(input())
tulis()
except:
print("u have typed character string,instead of integer")
