python3-sum()函数

sum(iterable, start=0, /)

Return the sum of a 'start' value (default: 0) plus an iterable of numbers

When the iterable is empty, return the start value.
This function is intended specifically for use with numeric values and may
reject non-numeric types.

返回一个“start”值(默认为0)加上一个可迭代的数字的和

当可迭代为空时,返回起始值。
此函数专门用于数值,可能会拒绝非数值类型。
 

square3 = [val for val in range(0,101)]

print(sum(square3))

>>结果:5050
(求和函数sum=(n*(n+1))/2)
