Python 替换第一个和最后一个字符之间的所有内容

Question

Not sure how to do this in a python way. But I want to replace the characters in a string in-between the first and last characters

For example, "apples" would be "a****s", and "car" would be "c*r".

Answer 1

This function assumes that the length of the input is at least 2, but you can use string indexing to get the first and last character, and then add the appropriate number of asterisks in between:

def replace_characters(s):
    return s[0] + '*' * (len(s) - 2) + s[-1]

print(replace_characters('apples')) # 'a****s'
print(replace_characters('car')) # 'c*r'
