如何使用Python在.txt文件中嵌套“替换的对象”

Question

我是Python的初学者。我正在尝试运行以下代码来替换.txt批注文件中的某些标签。

import os

dirname = "/home/masoud/masoud/Dataset/PID-CORRECTED/uncorrected-YOLO_darknet"
for txt_in in os.listdir(dirname):
    with open(os.path.join(dirname, txt_in)) as infile:
        for line in infile:
            word=line.split(" ")[0]#spliting the string and returning an array and returing the first item of array
            if word=="6":
                word=word.replace('6', '5')#it is only changing the word but not in the infile
            elif word=="9":
                word=word.replace('9', '6')
            elif word=="10":
                word=word.replace('10', '7')
            elif word=="11":
                word=word.replace('11', '8')
                #If the break statement is inside a nested loop (loop inside another loop), the break statement will terminate the innermost loop.
            else:
                continue
            break 

显然，它仅更改“ word”对象，而不更改“ infile”（每个.txt文件）内的内容。提前非常感谢您的帮助！我的.txt文件（即我的注释）如下所示：

10 0.31015625 0.634375 0.0890625 0.2625

9 0.37109375 0.35703125 0.0671875 0.2015625
