python实现1加到100

‘‘‘python实现任意数到任意数相加，如：1加到100‘‘‘

#第一种是for循环# def sum(start, end):#     sum = 0#     for one in range(start, end+1):#         sum = one + sum#         one += 1#     return sum## result = sum(1, 100)# print(result)

#第二种是while循环def sum2(start,end):    i = start    sum = 0    while i <= end:        sum += i        i += 1    return sum

result = sum2(-0.01,100.0009)print(result)

#第三种，导入模块的内建函数reduce，只能整数?# from functools import reduce# def sum(x, y):#     return x + y# result = reduce(sum, range(1,101))# print(result)
