如何在打开带有HTML标记的文本文件时使用替换命令

Question

我有一个名为front.txt:的文本文件

<a href="https://website/project_name.html" target="_blank">
<img src="https://website/project_name.webp" class="img img-responsive">

我正在尝试开发一个Python代码；项目名称"并将其替换为它们的名称。

这就是我所做的：

filename = 'front.txt'
with open(filename, 'r+') as f:
lines = f.readlines()
your_project_name = input("Project Name? ")
for line in lines:
line.replace("project_name", your_project_name)
print(line.strip())

当我运行Python程序时，它无法替换"project_name"。

Answer 1

Replace不就地操作，因此必须分配值才能使其工作。

filename = 'front.txt'
with open(filename, 'r+') as f:
lines = f.readlines()

your_project_name = input("Project Name? ")

for line in lines:
line = line.replace("project_name", your_project_name)
print(line.strip())
