预处理 python 中的文本数据

Question

There is a text file(a.text) such as the below example. For each data, I want to add some features like password length, number of uppercase letters, number of lowercase) and rename each file. How to coding in python?

(example) before

!2QqWwee

!Hihellohi!

1111111

12345678

(example) after

!2QqWwee, 8, 2, 4

!Hihellohi!, 11, 1, 8

11111111, 8, 0, 0

12345678, 8, 0, 0

Answer 1

You want this?

def UpperLower(each_password):
    CounterDict = {"UpperCount": 0, "LowerCount": 0}
    for each_character in each_password:
        if each_character.isupper():
           CounterDict["UpperCount"] += 1
        elif each_character.islower():
           CounterDict["LowerCount"] += 1
        else:
           pass
    print(each_password, len(each_password), CounterDict["UpperCount"], CounterDict["LowerCount"])

Passwords = ["!2QqWwee", "!Hihellohi!", "11111111", "12345678"]

for each_password in Passwords:
    UpperLower(each_password)

Results:

# !2QqWwee 8 2 4
# !Hihellohi! 11 1 8
# 11111111 8 0 0
# 12345678 8 0 0
