Question

我知道那里有很多关于阅读和写作的内容，但我仍然没有找到我需要的内容。

我有 5 个文件（即 in1.txt、in2.txt、in3.txt...），我想 open/read、运行通过我拥有的函数获取数据，然后将新的返回值输出到相应的新文件中（即out1.txt、out2.txt、out3.txt...）

我想在一个程序中做到这一点运行。我不确定如何编写循环来处理一个运行.

中的所有编号文件

Answer 1

如果您只是逐一查找运行，您可以执行以下操作：

import os

count = 0
directory = "dir/where/your/files/are/"
for filename in os.listdir(directory):
    if filename.endswith(".txt"):
        count += 1
        with open(directory + filename, "r") as read_file:
            return_of_your_function = do_something_with_data()
        with open(directory + count + filename, "w") as write_file:
            write_file.write(return_of_your_function)

Answer 2

如果你希望它们被串行处理，你可以使用如下的for循环：

inpPrefix = "in"
outPrefix = "out"
for i in range(1, 6):
    inFile = inPrefix + str(i) + ".txt"
    with open(inFile, 'r') as f:
        fileLines = f.readlines()

    # process content of each file
    processedOutput = process(fileLines)

    #write to file
    outFile = outPrefix + str(i) + ".txt"
    with open(outFile, 'w') as f:
         f.write(processedOutput)

注意：这假定输入和输出文件与脚本位于同一目录中。

Answer 3

给你！我会做这样的事情：
（假设所有输入的 .txt 文件都在同一个输入文件夹中）

input_path  = '/path/to/input/folder/'
output_path = '/path/to/output/folder/'

for count in range(1,6):
    input_file  = input_path  + 'in'  + str(count) + '.txt'
    output_file = output_path + 'out' + str(count) + '.txt'


    with open(input_file, 'r') as f:
        content = f.readlines() 
        output  = process_input(content)
    
    with open(output_file, 'w') as f:
        w.write(output)
