python开辟_textwrap文本样式

在看python的API的时辰,发明python的textwrap在处理惩罚字符串样式的时辰功能强大
在这里我做了一个demo:
textwrap供给了一些办法:
wrap(text, width = 70, kwargs):这个函数可以把一个字符串拆分成一个序列
1 textwrap import
2
3 #应用textwrap中的wrap()办法
4 def test_wrap():
5 test_str = 6 The textwrap module provides two convenience functions, wrap() and fill(), as well as 1
7 TextWrapper, the class that does all the work, and two utility functions, dedent() and indent(). If 2
8 you’re just wrapping or filling one or two text strings, the convenience functions should be good 3
9 enough; otherwise, you should use an instance of TextWrapper for efficiency. 4
10
11 print(wrap(test_str, 20))
12
13 def main():
14 test_wrap()
15
16 if __name__ == __main__:
17 main()
输出结果:
