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))
