将键入大量的字符串,变量,和格式化字符,并且将它们打印出来
代码如下
# coding: utf-8 __author__ = 'www.py3study.com' x = "There are {} types of people.".format(10) binary = 'binary' do_not = "don't" y = "Those who know {} and those who {}.".format(binary, do_not) print(x) print(y) print("I said: %r." % x) print("I also said: '{}'".format(y)) hilarious = False joke_evaluation = "Isn't that joke so funny ?! %r" print(joke_evaluation % hilarious) w = "This is the left side of..." e = "a string with a right side." print(w + e)
应该看到的结果
There are 10 types of people.
Those who know binary and those who don't.
I said: 'There are 10 types of people.'.
I also said: 'Those who know binary and those who don't.'
Isn't that joke so funny ?! False
This is the left side of...a string with a right side.
常见问题
%r用来做debug比较好,因为它会显示变量的原始数据(raw data),而其它的符号则是用来向用户显示输出的
