%(取模)操作符产生第一个参数除以第二个参数的余数。数值参数首先转换为公共类型。

3 + 2 + 1-5 + 4% 2-1/4 + 6 = 7

这基于运算符优先级。

在大多数语言中%表示模数。Python也不例外。

模运算符，通常用于整数的余数除法，但在Python中可用于浮点数。

http://docs.python.org/reference/expressions.html

The % (modulo) operator yields the remainder from the division of the first argument by the second. The numeric arguments are first converted to a common type. A zero right argument raises the ZeroDivisionError exception. The arguments may be floating point numbers, e.g., 3.14%0.7 equals 0.34 (since 3.14 equals 4*0.7 + 0.34.) The modulo operator always yields a result with the same sign as its second operand (or zero); the absolute value of the result is strictly smaller than the absolute value of the second operand [2].

模数-左手操作数除以右手操作数并返回余数。

如果有帮助的话:

1:0> 2%6
=> 2
2:0> 8%6
=> 2
3:0> 2%6 == 8%6
=> true

．.． 等等。

def绝对(c): 如果c > = 0: 返回c 其他: 返回c * 1 x=int(input("输入值")) 一个绝对(x) = print ()

%是模。3% 2 = 1,4% 2 = 0

/是除法(在本例中为整数)，因此:

3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6
1 + 4%2 - 1/4 + 6
1 + 0 - 0 + 6
7
