Question

with open('factory2.txt') as sf, open('target1.txt', 'w') as tf:
    i = -1
    for line in sf:
        if line.startswith('tmpobjid2a'):
            i += 1
        tf.write(line.replace('tmpobjid2a', f'tmpobjid2a[{i}]'))

我正在尝试使用它，但是i值根本没有改变，我在这里做错了什么？对于所有行，i值都表示为-1。即使它以'tmpobjid2a'开头的行通过了

您可以尝试

with open(source.txt) as sf, open(target.txt, 'w') as tf:
    i = -1
    for line in sf:
        if line.strip().startswith('alcatrazObj'):
            i += 1
        tf.write(line.replace('[]', f'[{i}]'))

是否可以自动更改.txt文件中每行的SPECIFIC PART？
