Python : Remove the key if its value is lower than 2

Question

There is a list containing 2 dictionaries, if I want to delete the key of 'zxc' that contains a value lower than 2, what should I do in the next step?

aa = [{'asd': 'qwe', 'zxc': 5}, {'zxc': 1, 'rty': 'uio'}]

def try_test():
    if 'zxc' < 2:
        del aa['zxc']

but it doesn't work.

Answer 1

The problem in your code is that aa is a list of dictionaries so aa['zxc'] is not clear.

Instead you should loop through each index in the list and compare as follows:

aa = [{'asd': 'qwe', 'zxc': 5}, {'zxc': 1, 'rty': 'uio'}]

def try_test():
    for ind in aa:
        if ind['zxc'] < 2:
            del ind['zxc']

    print(aa)

try_test()

Output:

[{'zxc': 5, 'asd': 'qwe'}, {'rty': 'uio'}]
