正则匹配点本身时，为啥匹配不到？

[amiwrong123]

import re

result = re.match("[\\.]+[\d]+", "...........................................761")
if result is None:
    print(result)
else:
    print("success")

当我执行如上程序时，匹配成功了。

import re

result = re.match("[\\.]+[\d]+", " ...........................................761")
if result is None:
    print(result)
else:
    print("success")

当我执行如上程序时，字符串前面多了个空格，却匹配失败了。

import re

result = re.match("[\\.]+[\d]+", "first chapter...........................................761")
if result is None:
    print(result)
else:
    print("success")

当我执行如上程序时，字符串前面多了个单词，却匹配失败了。

各位大佬，为啥会匹配失败呀？（正则比较菜，大家轻喷）

[If zero or more characters at the beginning of string match the regular expression pattern, return a corresponding Match]( https://docs.python.org/3/library/re.html#:~:text=If%20zero%20or%20more%20characters%20at%20the%20beginning%20of%20string%20match%20the%20regular%20expression%20pattern%2C%20return%20a%20corresponding%20Match)

match 是从头开始匹配，从中间开始匹配用 re.search
