Python input()函数报TypeError：不接受关键字参数的问题求助

Python的input()函数只接受单个字符串参数，不支持像print()那样传入多个参数和sep关键字参数。你代码里给input()传了多个字符串、变量a以及sep=""，这就触发了TypeError。

另外你代码里的变量a初始为0，但循环中没有更新，会导致每次询问的都是workout #0，这也是需要修正的点。

这里提供几种可行的写法：

方法1：使用f-string（推荐，简洁直观） #

workouts = int(input("How many workouts do you have data for?\n"))

for i in range(workouts):
    # 用i+1是因为range从0开始，要显示第1、2...次训练
    sets = int(input(f"How many sets were completed in workout #{i+1}?\n"))
    # 这里可以添加处理sets的逻辑，比如累加统计等

方法2：字符串拼接 #

workouts = int(input("How many workouts do you have data for?\n"))
a = 1  # 初始化为1，对应第一次训练

for _ in range(workouts):
    sets = int(input("How many sets were completed in workout #" + str(a) + "?\n"))
    a += 1  # 每次循环后更新训练次数

方法3：使用str.format() #

workouts = int(input("How many workouts do you have data for?\n"))

for i in range(workouts):
    sets = int(input("How many sets were completed in workout #{0}?\n".format(i+1)))

• 所有修正后的写法都只给input()传了一个完整的字符串参数，避免了原错误。
• 循环中用i+1或者更新a的值，确保询问的训练次数是正确的（从1开始递增）。
