i = 0
while i <= 100:
sum += i
i += 1
print(sum)
i = 0
while i <= 100:
sum += i
i += 1
print(sum)
上述代码报错:
TypeError: unsupported operand type(s) for +=: 'builtin_function_or_method' and 'int'
关于上述提示错误:是因为在Python中不需像C一样,需要 int sum (指定sum的类型),但并不是说可以直接放在表达式中去计算,所以还是需要先定义的(这些都是小细节,平时都应该尽量避免,做好类似问题的收集),即正确的代码如下所示:
#-*- coding : utf-8 -*-
i = 0
sum = 0
while i <= 100:
sum += i
i += 1
print(sum)
i = 0
sum = 0
while i <= 100:
sum += i
i += 1
print(sum)
