Question

我正在处理一个作业问题，该问题采用逗号分隔值的列表，将其转换为列表，然后对所述列表中的最大值和最小值求和。

def max_min_sum():
    user_input = input("Please enter a comma seperated list of numbers")
    input_as_a_list = user_input.split(",")
    input_as_numbers = map(float, input_as_a_list)
    print(sum((min(input_as_numbers))+(max(input_as_numbers, default = 0))))
max_min_sum()

现在我收到此错误：

TypeError: 'float' object is not iterable

我也尝试过：

def max_min_sum():
    user_input = input("Please enter a comma seperated list of numbers")
    input_as_a_list = user_input.split(",")
    input_as_numbers = map(float, input_as_a_list) 
    print((min(input_as_numbers) + max(input_as_numbers, default = 0)))    
max_min_sum()

但是现在它只是给我最小值。

您的代码中至少有2个错误，请参阅以下注释查看此修复程序：

def max_min_sum():
    user_input = input("Please enter a comma seperated list of numbers")
    input_as_a_list = user_input.split(",")
    # map returns a generator, so you need to consume the output first
    # Or, you'll endup with max == 0
    # Or, better using a list comprehension
    # input_as_numbers = [float(elm) for elm in input_as_a_list]
    input_as_numbers = list(map(float, input_as_a_list))
    # No need to use sum, you're already using + operator
    print(min(input_as_numbers)) + max(input_as_numbers, default = 0))

max_min_sum()

汇总列表的最大和最小
