It’s more about python list comprehension syntax. I’ve got a list comprehension that produces list of odd numbers of a given range:
[x for x in range(1, 10) if x % 2]
This makes a filter – I’ve got a source list, where I remove even numbers (if x % 2
). I’d like to use something like if-then-else here. Following code fails:
>>> [x for x in range(1, 10) if x % 2 else x * 100]
File "<stdin>", line 1
[x for x in range(1, 10) if x % 2 else x * 100]
^
SyntaxError: invalid syntax
There is a python expression like if-else:
1 if 0 is 0 else 3
How to use it inside a list comprehension?
