练习代码如下
# coding: utf-8
__author__ = 'www.py3study.com'
formatter = "{} {} {} {}"
print(formatter.format(1, 2, 3, 4))
print(formatter.format('one', 'two', 'three', 'four'))
print(formatter.format(True, False, False, True))
print(formatter.format(formatter, formatter, formatter, formatter))
print(formatter.format(
"I had this thing.",
"That you could type up right.",
"But it didn't sing.",
"So I said goodnight.")
)
应该看到的结果
1 2 3 4
one two three four
True False False True
{} {} {} {} {} {} {} {} {} {} {} {} {} {} {} {}
I had this thing. That you could type up right. But it didn't sing. So I said goodnight.
常见问题
为什么"one"要用引号,而True和False不需要?
因为True和False是python关键字,用来表示真假的意义,如果加了引号,就变成了字符串,也就无法实现它们本来的功能
