string - Differentiating Python variables as str or int - Stack Overflow
how are you supposed to add an integer to a string?
How to think about integers, strings, and floats?
Str vs Int
The first point is that you need some rule that tells you which values are integers and which ones aren't. In a data set that includes things like 32s, I'm not sure it makes sense to just treat anything that could be an integer as if it were.
But, for simplicity, let's assume that is the rule you want: anything that could be an integer is. So, int(a) is already pretty close; the only issue is that it can fail. What do you do with that?
Python is designed around EAFP: it's Easier to Ask Forgiveness than Permission. Try something, and then deal with the fact that it might fail. As Cyber suggests, with a try statement:
try:
intvalue = int(a)
except ValueError:
# Oops, it wasn't an int, and that's fine
pass
else:
# It was an int, and now we have the int value
maxvalue = max(maxvalue, intvalue)
isalpha() Returns "True" if all characters in the string are in the alphabet
isnumeric() Returns "True" if all characters in the string are numeric
so;
data="Hello World"
print(data.isnumeric()) #it will retuns with False
print(data.isalpha()) # True
Sorry for my soulles answer, I just came here for same issue, I found a different way and wanted to share with you
im new to python and trying to learn how to print the sum of a integer and a string number, i get an error that says| unsupported operand type(s) +: 'int' and 'str' | i dont know how to solve it and everything i look up only has for int + int so im wondering if i have to just convert the string to a integer and if so how would that be done but if thats not what i need to do i would also really appreciate an explanation.
