python判断

a = 2b = 1if a > b: print(a)else: print(b)多个if语句a = 2b = 1if a > b: print(a)elif a == b: print(b)elif a < b: print(a)三元表达式print(a if a > b else b) #打印a如果a大于b的话，否则打印b循环

有2种方式，for x in list,tutle，另一种是while循环打印1到100的整数和sum = 0for i in range(1, 101): sum += iprint(sum)sum = 0i = 0while i < 101: sum += i i += 1print(sum)break和continue，break是跳出当前循环，而continue是跳过本次循环，开启下一次循环sum = 0i = 0while i < 101: if i % 2 == 0: #跳过偶数，求出奇数和 i += 1 continue else: sum += i i += 1print(sum)sum = 0i = 0while i < 101: if i % 2 == 0: i += 1 break else: sum += i i += 1print("i的值为:", i) #最后i的值是1print(sum)
