python - 正则表达式：从字符串中删除's？

Question

字符串输入：Python's Programming: is very easy to learn

预期输出：Python Programming: is very easy to learn

这是我到目前为止没有工作的内容：

import re
mystr = "Python's Programming: is very easy to learn"
reg = r'\w+'
print(re.findall(reg, mystr))

如何删除'sfrom python's？

Answer 1

您提取一个或多个字母数字字符的所有匹配项。

利用

\b's\b

见证明。

说明：

--------------------------------------------------------------------------------
  \b                       the boundary between a word char (\w) and
                           something that is not a word char
--------------------------------------------------------------------------------
  's                       '\'s'
--------------------------------------------------------------------------------
  \b                       the boundary between a word char (\w) and
                           something that is not a word char

蟒蛇代码：

import re
mystr = "Python's Programming: is very easy to learn"
print(re.sub(r"\b's\b", '', mystr))
