Python正则表达式以匹配文件名。 使用os.walk（）获取文件名

Question

I'm using os.walk() to get files name. What I need to do is to create a list with files name that match following patterns:

if '*' will match all files.

if 'h*' will match all files beginning with h.

if '*h' will match all files ending with h.

if '*h*' will match all files that have h in them.

if [hw]* will match any one character in set, including set negation [^hw]

I'm new with regular expression and I have troubles with creating an if statement for this issue. May some explain it to me (maybe with code examples) how to do it. Thanks.

I tried fnmatch , and it's working perfectly, a Big Thanks to Charles Duffy . Here is my code:

for dp, dn, filenames in os.walk(path):
    for ff in filenames:
        if fnmatch.fnmatch(ff, 'My patterns here'):
             list.append(os.path.join(dp, ff))
