数学里面的加减乘除,就是运算符,但是 Python 的运算符更多样,更复杂,分为算术运算符.比较运算符.赋值运算符.位运算符.逻辑运算符.成员运算符.身份运算符.为了更直观的看到运算符的使用,本文采用代码和注释结合的方式进行讲解. 算术运算符 a = 21 b = 10 c = 0 # 加 c = a + b # 31 # 减 c = a - b # 11 # 乘 c = a * b # 210 # 除 c = a / b # 2.1 # 求余数 c = a % b # 1 # 幂(次方) a
import random from random import choice ops = ('+','-','×','÷') ans = [] i=0 while i < 100 : op1 = choice(ops) op2 = choice(ops) n = random.randint(1,9) if op1 == '+' and op2 == '+' : a = random.randint(0,100) b = random.randint(0,100-a) c = random.r
