Why this code is invalid?

Question

print(int('034'+'56')) #valid code
print(int('34'+'3.4')) #invalid code but why can you tell me?

Answer 1

In Python you cannot convert a float that is written as a String directly to an integer.
Here:
int("34") : legal
int(34.6) : legal
int("34.6"): illegal
float("34.6"): legal

If you have a float as a String and you want it converted to an int. First convert the String to a float. Then convert the resulting float to an int.

Answer 2

There is a "," in the second line. If you remove it the second number is a float.

This line works:
print(int(float('34'+'3.4')))

Answer 3

Your string makes a float. I think it cannot be converted to an integer directly.

Answer 4

oh my god. That is so me. :-p
