The objective is to create a clean dictionary key: values pair removing a pattern contained in a list.
i.e

pattern_list = ['_PATTERN1','_PATTERN2']
test_dictionary = {'x_PATTERN1': '1', 'y_PATTERN2': 'Okay...'}
#desired result
test_dictionary = {'x': '1', 'y': 'Okay...'}

Have done in the past dict comprehension using this pattern

{k.replace('.', '') : v.replace('.', '') for k, v in x.items()}

However, I wonder how can I use a list instead of a single pattern there.

Solution

how about a own function to clean keys?

pattern_list = ['_PATTERN1','_PATTERN2']
def clean_key(key):
    for pattern in pattern_list:
        key = key.replace(pattern, "")
    return key
{clean_key(k) :  v for k, v in x.items()}
