正则表达式查找带有数字和字母的单词（哈希）

Question

I have a set of strings and some of them has "words" with numbers and letters, for example:

Revert Push Diamond tick mark classes to Eclipse This reverts commit 4086b8666cdc839b5ec7e7bfff0ae1b9695542ff .......

Is there some regex expression to remove these words (hash)?

Answer 1

You could look for sequences of hex characters delimited with whitespace of a required length, eg between 30 and 50 characters. For example:

import re

text = """Revert Push Diamond tick mark classes to Eclipse This reverts commit 
4086b8666cdc839b5ec7e7bfff0ae1b9695542ff .......
Another test
48a8b89d9f8e80a938f8ab487de09ff
"""

for hash in re.findall(r'\s+([0-9a-fA-F]{30,50})\s+', text):
    print(hash)

Would display:

4086b8666cdc839b5ec7e7bfff0ae1b9695542ff
48a8b89d9f8e80a938f8ab487de09ff
