How i can set the increasing of enumerate, that depends on condition?

I have got the following loop^ 

i = 0
for var in vars:
    if var[ "ID" ] != 0 and var[ "ID" ] & 1:
        print i, var[ "ID" ]
        i += 1

Can I use enumerate for this loop instead of counter i ? How i can set the increasing of enumerate, that depends on this condition: if var[ "ID" ] != 0 and var[ "ID" ] & 1:

Solution

  • You may use filter:

    >>> vs = [{'ID': 1}, {'ID': 4}]
>>> for i, v in enumerate(filter(lambda x: x['ID'] & 1, vs)):
...     print i, v
...
0 {'ID': 1}
