How to check python str object can be translated into int object.

Question

Or same output will be get after translating into int object in python3.

Answer 1

Use exception handling mechanism

string= "welcome world"
try:
i = int( string )
except ValueError:
i = 0 # or any default number you want
print( i )

You can turn this into function and use it whenever you see a conversion failure is a possibility.
