在Python中更改文件扩展名 [英] Changing file extension in Python

问题描述

假设使用CGI从index.py起，我已发布文件foo.fasta来显示文件.我想在显示文件中将foo.fasta的文件扩展名更改为foo.aln.我该怎么办?

解决方案

os.rename()

例如:

# renamee is the file getting renamed, pre is the part of file name before extension and ext is current extension
pre, ext = os.path.splitext(renamee)
os.rename(renamee, pre + new_extension)

Suppose from index.py with CGI, I have post file foo.fasta to display file. I want to change foo.fasta's file extension to be foo.aln in display file. How can I do it?

解决方案

os.path.splitext(), os.rename()

for example:

# renamee is the file getting renamed, pre is the part of file name before extension and ext is current extension
pre, ext = os.path.splitext(renamee)
os.rename(renamee, pre + new_extension)
