[英]Iterate through all files in a directory and find and replace text - Python
Baby brand new. 宝贝全新。 This was Frankenstein'ed together from a few similar topics, none of which seemed to cover the necessary step of nesting a find and replace inside a file loop.
这是弗兰肯斯坦(Frankenstein)从几个类似的主题中总结出来的,似乎都没有涵盖在文件循环内嵌套查找和替换的必要步骤。
I am attempting to iterate through every file in a folder (not recursively, I only have one folder level) of a specific type (listed here as a '.LIC') and replace a short bit of text. 我试图遍历特定类型(此处列为“ .LIC”)的文件夹中的每个文件(不是递归地,我只有一个文件夹级别),并替换一小段文本。 The following is as close as I could come:
以下是我可能接近的内容:
import glob, os, fileinput
from glob import glob
root_dir = r"myPath"
os.chdir(root_dir)
for file in glob, glob('*.LIC'):
filename = str(file)
with fileinput.FileInput(filename, inplace=True, backup='.bak') as file:
for line in file:
print(line.replace('findText', 'replaceText'), end='')
As you can imagine this went swimmingly. 可以想象,这一切顺利进行。 The error code is placed below.
错误代码位于下面。
OSError Traceback (most recent call last)
<ipython-input-61-e2fd0e9a5df9> in <module>()
6 filename = str(file)
7 with fileinput.FileInput(filename, inplace=True, backup='.bak') as file:
----> 8 for line in file:
9 print(line.replace('findText', 'replaceText'), end='')
10
C:\Users\Me\Anaconda3\lib\fileinput.py in __next__(self)
246 def __next__(self):
247 while True:
--> 248 line = self._readline()
249 if line:
250 self._filelineno += 1
C:\Users\Me\Anaconda3\lib\fileinput.py in _readline(self)
333 pass
334 # The next few lines may raise OSError
--> 335 os.rename(self._filename, self._backupfilename)
336 self._file = open(self._backupfilename, self._mode)
337 try:
OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: '<function glob at 0x00000000013D3400>' -> '<function glob at 0x00000000013D3400>.bak'
I think my problem is nesting a reference to 'file', but I am unsure how to resolve this. 我认为我的问题是嵌套对“文件”的引用,但是我不确定如何解决此问题。
Thank you for the help in advance. 谢谢您的帮助。
You should loop over the result of glob
and not a tuple with the function object glob
: 您应该遍历
glob
的结果,而不是使用功能对象glob
的元组:
for filename in glob('*.LIC'):
with fileinput.FileInput(filename, inplace=True, backup='.bak') as file:
for line in file:
print(line.replace('findText', 'replaceText'), end='')
