Answer 1

You can use a list comprehension with a condition on the case:

out = [item for item in data_list if sum(map(str.isupper, item))==2]

explanation:

For each item in the list, map the str.upper function to each character and count the number of uppercase using sum. If the count is equal to 2, keep the item.

output:

['HaH',
 'iariKakdaQ',
 'xkaryTR4',
 'hasWesW',
 'irajYta2W',
 'sdeWKrai',
 'aKajQ',
 'kadYT',
 'LqdhariT']
