[Solved] Python List parsing (incude int, str)

by


This is the way to go:

x = ['2', '3/4', '+', '4', '3/5']
g = []
for i in x:
    try:
        g.append(int(i))
    except ValueError:
        pass
print(g)  # [2, 4]

What you tried is not a try-except block. It is an if statement which failed because '4' is not an int instance (4 is, notice the quotes); it is a string.

There are of course other ways to do it too as mentioned in the comments. I only went for the try-except because you mentioned it in your comments.
