一、迴圈

1、for

names = [‘Michal‘, ‘Bob‘, ‘tracy‘]for name in names:    print(name)sum = 0for x in [1, 2, 3, 4, 5, 6, 7,8,9,10]:    sum = sum + x    print(sum)# 列印數字 0 - 9for x in range(10):    print(x)

 

2、while

sum = 0n = 99while n > 0:    sum = sum + n    n = n - 2    print(sum)n = 1while n <= 100:    if n > 10:  # 當n = 11時，條件滿足，執行break語句        break    # break語句會結束當前迴圈    print(n)    n = n + 1print("end")n = 0while n < 10:    n = n + 1    if n % 2 == 0:  # 如果n是偶數，執行continue語句        continue   # continue語句會直接繼續下一輪迴圈，後續的print()語句不會執行    print(n)# 計算1+2+3+...+100:sum = 0n = 1while n <= 100:    sum = sum + n    n = n + 1print(sum)# 計算1x2x3x...x100:acc = 1n = 1while n <= 100:    acc = acc * n    n = n + 1print(acc)
