我正在尝试将特定行添加到文件中的特定区域。
我正在使用这个：
new_file = open("file.txt", "r+")
for line in new_file:
if line == "; Include below":
line = line + "\nIncluded text"
new_file.write(line)
else:
new_file.write(line)
但由于某种原因我的内容file.txt正在重复。
编辑：如果我的文件如下所示：
blablablablablablabal
balablablabalablablbla
include below
blablablablablabalablab
ablablablabalbalablaba
我想让它看起来像：
blablablablablablabal
balablablabalablablbla
include below
included text
blablablablablabalablab
ablablablabalbalablaba
读取时无法安全地写入文件，最好将文件读入内存，更新它，然后将其重写到文件。
with open("file.txt", "r") as in_file:
buf = in_file.readlines()
with open("file.txt", "w") as out_file:
for line in buf:
if line == "; Include this text\n":
line = line + "Include below\n"
out_file.write(line)
