你知道有什么图书馆能帮你吗?
我将编写一个函数,以统一的diff格式打印两个多行字符串之间的差异。像这样的:
def print_differences(string1, string2):
"""
Prints the comparison of string1 to string2 as unified diff format.
"""
???
使用示例如下:
string1="""
Usage: trash-empty [days]
Purge trashed files.
Options:
--version show program's version number and exit
-h, --help show this help message and exit
"""
string2="""
Usage: trash-empty [days]
Empty the trash can.
Options:
--version show program's version number and exit
-h, --help show this help message and exit
Report bugs to http://code.google.com/p/trash-cli/issues
"""
print_differences(string1, string2)
这应该会打印出类似的内容:
--- string1
+++ string2
@@ -1,6 +1,6 @@
Usage: trash-empty [days]
-Purge trashed files.
+Empty the trash can.
Options:
--version show program's version number and exit
我就是这样解决的:
你看过内置的python模块difflib吗? 看看这个example
