[N00B]什么是％？ [英] [N00B] What's %?
问题描述
嗨！它已经有一个星期的时间学习python了！
我已经阅读了''绝对优势的python编程''
我不明白％喜欢......
107％4 = 3
7％3 = 1
我是与师混淆：/
请帮帮我...
thx 4阅读。

107％4 = 3
7％3 = 1
它是模数运算符。它返回整数
除法的余数。正如我们以前在二年级时说的那样：
4进入107 26次，剩下3次。
3进入4次2次剩下1个。

我会是RITA HAYWORTH !!或者

我不明白％喜欢......
107％4 = 3
7％3 = 1
我对分歧很困惑：/
这不是分裂;除法运算符是''/''。这是mod
函数，它返回余数 - 例如，7除以3是
2余数1，所以7％3返回1.

107％4 = 3
7％3 = 1
它是模数运算符（如果你不记得，模数是
剩余的整数除法，即5％2 = 1）
最常用的一个用于测试数字是奇数还是偶数：
any_even_number％2 == 0
any_odd_number％2 == 1
注意％运算符也用于字符串格式化，即：
"％d modulo％d =％d" ％（5,2,1）
=> 5模2 = 1

Hi! it''s been about a week learning python!
I''ve read ''python programming for the absolute begginer''
I don''t understand about % like...
107 % 4 = 3
7 % 3 = 1
I''m confused with division :/
Please help me...
thx 4 reading.

It''s the modulus operator. It returns the remainder of integer
division. As we used to say in second grade:
4 goes into 107 26 times with 3 left over.
3 goes into 4 2 times with 1 left over.

It''s not division; the division operator is ''/''. It''s the mod
function, which returns the remainder - for example, 7 divided by 3 is
2 remainder 1, so 7 % 3 returns 1.

it''s the modulo operator (if you don''t remember, the modulo is the
remaining of the integer division, ie 5 % 2 = 1)
One of the most commun use is to test wether a number is odd or even:
any_even_number % 2 == 0
any_odd_number % 2 == 1
Note that the % operator is also used for string formating, ie:
"%d modulo %d = %d" % (5, 2, 1)
=> "5 modulo 2 = 1"
