有没有更好的方法来使用glob。Glob在python中获取多个文件类型的列表，如.txt， .mdown和.markdown?现在我有这样的东西:
projectFiles1 = glob.glob( os.path.join(projectDir, '*.txt') )
projectFiles2 = glob.glob( os.path.join(projectDir, '*.mdown') )
projectFiles3 = glob.glob( os.path.join(projectDir, '*.markdown') )
当前回答
Glob返回一个列表:为什么不只是多次运行它并连接结果呢?
from glob import glob
project_files = glob('*.txt') + glob('*.mdown') + glob('*.markdown')
其他回答
import glob
import pandas as pd
df1 = pd.DataFrame(columns=['A'])
for i in glob.glob('C:\dir\path\*.txt'):
df1 = df1.append({'A': i}, ignore_index=True)
for i in glob.glob('C:\dir\path\*.mdown'):
df1 = df1.append({'A': i}, ignore_index=True)
for i in glob.glob('C:\dir\path\*.markdown):
df1 = df1.append({'A': i}, ignore_index=True)
import os
import glob
projectFiles = [i for i in glob.glob(os.path.join(projectDir,"*")) if os.path.splitext(i)[-1].lower() in ['.txt','.markdown','.mdown']]
Os.path.splitext将返回filename & .extension
filename, .extension = os.path.splitext('filename.extension')
.lower()将字符串转换为小写
使用扩展列表并遍历
from os.path import join
from glob import glob
files = []
extensions = ['*.gif', '*.png', '*.jpg']
for ext in extensions:
files.extend(glob(join("path/to/dir", ext)))
print(files)
与@BPL相同的答案(计算效率高)，但它可以处理任何glob模式，而不是扩展:
import os
from fnmatch import fnmatch
folder = "path/to/folder/"
patterns = ("*.txt", "*.md", "*.markdown")
files = [f.path for f in os.scandir(folder) if any(fnmatch(f, p) for p in patterns)]
这种解决方案既高效又方便。它还与glob的行为紧密匹配(请参阅文档)。
注意，使用内置包pathlib会更简单:
from pathlib import Path
folder = Path("/path/to/folder")
patterns = ("*.txt", "*.md", "*.markdown")
files = [f for f in folder.iterdir() if any(f.match(p) for p in patterns)]
这么多的答案都建议全局替换和扩展的数量一样多，我更喜欢只替换一次:
from pathlib import Path
files = (p.resolve() for p in Path(path).glob("**/*") if p.suffix in {".c", ".cc", ".cpp", ".hxx", ".h"})
