对多个文本文件使用相同的代码，并使用python生成多个文本文件作为输出

我有30多个文本文件。我需要对每个文本文件进行一些处理，然后用不同的名称将它们再次保存在文本文件中

示例1:precise_case_words.txt-processing-precise_case_句子.txt

示例2:random\u case\u words.txt-processing-random\u case\u句子.txt

像这样，我需要做的所有文本文件

现行代码：

我一直在手动复制并粘贴此代码，每次都手动更改名称。请给我建议一个避免使用python手工作业的解决方案。

假设您的*\u case\u words.txt都在当前目录中

import glob

in_file = glob.glob('*_case_words.txt')

prefix = [i.split('_')[0] for i in in_file]

for i, ifile in enumerate(in_file):
    data = []
    with open(ifile, 'r') as f:
        for line in f:
            data.append(line)
    with open(prefix[i] + '_case_sentence.txt' , 'w') as f:
        f.write(data)

这应该让您了解如何处理它：

def rename(name,suffix):
    """renames a file with one . in it by splitting and inserting suffix before the ."""
    a,b = name.split('.')             
    return ''.join([a,suffix,'.',b])  # recombine parts including suffix in it

def processFn(name):
    """Open file 'name', process it, save it under other name"""    
    # scramble data by sorting and writing anew to renamed file            
    with open(name,"r") as r,   open(rename(name,"_mang"),"w") as w:
        for line in r:
            scrambled = ''.join(sorted(line.strip("\n")))+"\n"
            w.write(scrambled)

# list of filenames, see link below for how to get them with os.listdir() 
names = ['fn1.txt','fn2.txt','fn3.txt']  

# create demo data
for name in names:
    with open(name,"w") as w:
        for i in range(12):
            w.write("someword"+str(i)+"\n")

# process files
for name in names:
    processFn(name)

有关文件列表：请参阅

我选择逐行读/写，您可以完全读取一个文件，处理它，然后根据您的喜好在块上再次输出它

fn1.txt：

进入fn1_mang.txt：

就在今天，我碰巧写了一篇这样的文章。

将功能抽象为一个函数，并在循环中调用它

def rename(name,suffix):
    """renames a file with one . in it by splitting and inserting suffix before the ."""
    a,b = name.split('.')             
    return ''.join([a,suffix,'.',b])  # recombine parts including suffix in it

def processFn(name):
    """Open file 'name', process it, save it under other name"""    
    # scramble data by sorting and writing anew to renamed file            
    with open(name,"r") as r,   open(rename(name,"_mang"),"w") as w:
        for line in r:
            scrambled = ''.join(sorted(line.strip("\n")))+"\n"
            w.write(scrambled)

# list of filenames, see link below for how to get them with os.listdir() 
names = ['fn1.txt','fn2.txt','fn3.txt']  

# create demo data
for name in names:
    with open(name,"w") as w:
        for i in range(12):
            w.write("someword"+str(i)+"\n")

# process files
for name in names:
    processFn(name)

someword0
someword1
someword2
someword3
someword4
someword5
someword6
someword7
someword8
someword9
someword10          
someword11
