2.数字运算

#数字运算: 加+ 减- 乘* 除/print(8+5)print(8-5)print(8*5)print(8/5)#数字运算: 整数除法// 只取整数print(8//5)#数字运算: 连续运算 (先乘除后加减)print(8+8*5)print((8+8)*5)number = 8print(number*5)#取余数 %print(number%5)#数字转换成字串 str(数字) 无法跟数字运算print("会印出数字" + str(number))#取绝对值absnumber = -8print(abs(number))#次方pow(基数,次方数) 零次方=1print(pow(5,2))print(pow(5,0))#找最大值 max()print(max(2135,3125,5231,1325,33252.111))#找最大值 min()print(min(2135.2,3125,5231,1325.25555,33252.111))#4捨5入 round()print(round(31.6))from math import *#无条件捨去 floor()print(floor(31.6))#无条件进位 ceil()print(ceil(33.33))#开根号 sqrtprint(sqrt(25))
