python copy files by wildcards
提问by Johnny
I am learning python (python 3) and I can copy 1 file to a new directory by doing this
我正在学习 python (python 3)，我可以通过这样做将 1 个文件复制到一个新目录
import shutil
shutil.copyfile('C:/test/test.txt', 'C:/lol/test.txt')
What I am now trying to do is to copy all *.txt files from C:/ to C:/test
我现在要做的是将所有 *.txt 文件从 C:/ 复制到 C:/test
*.txt is a wildcard to search for all the text files on my hard drive
*.txt 是一个通配符，用于搜索我硬盘上的所有文本文件

Use glob.glob()to get a list of the matching filenames and then iterate over the list.
使用glob.glob()来获取匹配文件名列表，然后遍历列表。

for file in glob.glob(r'C:/*.txt'):
print(file)
shutil.copy(file, dest_dir)

I am using python 2.7 test first to make sure it will work. I used the wildcard * because I add the date to all my text files. filename1_2016_04_18.txt Also some of the text files have different end users attached to the text file. filename2_username.txt
我首先使用 python 2.7 测试来确保它可以工作。我使用通配符 * 因为我将日期添加到我的所有文本文件中。filename1_2016_04_18.txt 还有一些文本文件有不同的最终用户附加到文本文件。文件名2_用户名.txt
import os, glob
directorypath = 'C:\Program Files\Common Files'
os.chdir(directorypath)
files = ['filename1', 'filename2', 'filename3']
print ('A %(files)s'% vars())
for filename in files:
file1 = filename + "*" + "." + "txt"; print ('1 %(file1)s'% vars())
file2 = ('%(file1)s') % vars (); print ('2 %(file2)s'% vars())
file3=glob.glob(file2); print ('3 %(file3)s'% vars())
for filename4 in file3:
try:
if os.path.isfile(filename4):
print ('I am deleteing this file %(filename4)s'% vars())
os.remove(filename4)
else: ## Show an error ##
print("Error can not delete text file : %s because file not found" % filename4)
except OSError, e: ## if failed, report it back to the user ##
print ("Error: %s - %s." % (e.filename,e.strerror))
