Solve "ValueError invalid literal for int() with base 10" - Python
Normally “ValueError: invalid literal for int()
with base 10” error occurs when we try to convert an invalid object into an integer.
The cases are,
- Passing a string containing anything that is not a number, like letters and special characters.
- Passing a string-type object that looks like a float type.
Example
int_var = int("...")
The solution is to ensure that we do not pass any letters or special characters to int()
function.
Solution 1
import re
myInput= "123a"
matched=re.search("[^\d]",myInput)
if matched==None:
myInt=int(myInput)
print("Output Integer is:")
print(myInt)
else:
print("Input Cannot be converted into Integer.")
Solution 2
myInput= "123a"
if myInput.isdigit():
print("Output Integer is:")
myInt=int(myInput)
print(myInt)
else:
print("Input cannot be converted into integer.")
