Python的format语法,可以用在两个场景:一个是{}.format中,另一个是f-string中,`f{xxx}'中,只不过后者支持外部定义的变量: # .format way 1 print('Hello {}!'.format('World')) # .format way 2 print('Hello {name}!'.format(name='World')) # f-string name = 'World' print(f'Hello {nam...
Python用format格式化字符串 - Xjng - 博客园 6.1. string - Common string operations - Python 3.6.4 documentation 在学习Python的过程中,我们常常会使用print语句,用于字符串输出。一般情况下,我们是这么使用的: >>>print('hello world')helloworld>>>print('hello%s'%('world'))helloworld ...
% (10,'hello',20,9.3)'|hello | 9.3|'>>>参考资料：http://docs.python.org/library/stdtypes.html#string-formatting-operations声明在字符串参数前面需要一个长度参数例如:'[%*s]' % (10,'a')==> '[ a]'
