how to check if a variable is integer?

Question

how can I check in a statement if a variable is an integer?

like for string, we can say:

if i == " "
    return something

how would I say: if i == integer??

Answer 1

Like this:

if type(i) == int:
     do_this()

Or like this:

if isinstance(i, int):
     do_this()

You will find more info here: What's the canonical way to check for type in Python? (of which I think your question is a duplicate)

Answer 2

Using isinstance:

for kee, val in valStore.items():
     if isinstance(key, int):
          writehist.writerow([key] + [val])
