爲什麼下面的Python不工作？

Question

下面的Python代碼被寫入生成對55 1之間的三角數字，但編碼不工作，爲什麼？

num = 1 
sum = 0 
while (num <= 10) 
    sum = sum + num 
    num = num + 1 
print (sum, end=' ') 

Answer 1

缺少冒號：

num = 1 
sum = 0 
while (num <= 10): 
    sum = sum + num 
    num = num + 1 
print (sum, end=' ') 

或

num = 1 
sum = 0 
while (num <= 10): 
    sum = sum + num 
    num = num + 1 
    print (sum, end=' ') 

輸出

1 3 6 10 15 21 28 36 45 55 

對於2.7

num = 1 
sum = 0 
while (num <= 10): 
    sum = sum + num 
    num = num + 1 
    print sum, 

Answer 2

你的錯誤是，默認情況下不使用Python 2.x的支持是不跟while語句錯誤，隨後()包裝和印刷結束

更正後的代碼是：

num = 1 
sum = 0 
while (num <= 10): 
    sum = sum + num 
    num = num + 1 

print sum
