如何在python中修改列表元素

Question

给定文件名列表，我们希望将所有扩展名为 .hpp 的文件重命名为扩展名 h。为此，我们希望生成一个名为 newfilenames 的新列表，其中包含新文件名。使用您迄今为止学到的任何方法填充代码中的空白，例如 for 循环或列表推导式。

filenames = ["program.c", "stdio.hpp", "sample.hpp", "a.out", "math.hpp", "hpp.out"]
# Generate newfilenames as a list containing the new filenames
# using as many lines of code as your chosen method requires.

---

print(newfilenames) 
# Should be ["program.c", "stdio.h", "sample.h", "a.out", "math.h", "hpp.out"]

Answer 1

newfilenames = [e.replace('.hpp','.h') for e in filenames]
