Splitting on / inside a list in Python

Question

I've got a list that contains the following:

x = ['1', '2/keys', '3']

Now the '2/keys' must be splitted. I figured it should be possible to make a list in a list? But before splitting, I've got to check if there's a "/" at all.

The following code, that obviously doesn't work, is what I've got:

for numbers in x:
            if '/' in x:
                x[numbers].split('/')

Is it possible to have an outcome like:

x = ['1', ['2', 'keys'], '3']

Answer 1

You are very close.

x = ['1', '2/keys', '3']
for ind, numbers in enumerate(x):
    if '/' in numbers:
        x[ind] = numbers.split('/')
print(x)

Or a list comprehension

Ex:

x = [numbers.split('/') if '/' in numbers else numbers for numbers in x]
