1.通过html 比较diff_text两文本不同之处

#!/usr/bin/env python

import difflib

text1 = """text1:

This module provides classes and functions for comparing sequences.

including HTML and context and unified diffs.

difflib document v7.4

add string

"""

text1_lines = text1.splitlines()

text2 = """text2:

This module provides classes and functions for Comparing sequences.

including HTML and context and unified diffs.

difflib document v7.5

"""

text2_lines = text2.splitlines()

d = difflib.HtmlDiff()

print d.make_file(text1_lines, text2_lines)

2. 通过差异关系符比较

#!/usr/bin/env python

import difflib

text1 = """text1:

This module provides classes and functions for comparing sequences.

including HTML and context and unified diffs.

difflib document v7.4

add string

"""

text1_lines = text1.splitlines()

text2 = """text2:

This module provides classes and functions for Comparing sequences.

including HTML and context and unified diffs.

difflib document v7.5

"""

text2_lines = text2.splitlines()

d = difflib.Differ()

diff = d.compare(text1_lines, text2_lines)

print '\n'.join(list(diff))
