Python 将列表转换为字符串的程序

Question

I have a list list = ["Num1","Num2","Num3"] how can I convert list to string like: Num1 => avg(Num1) as ABC I found function join but I can't convert

Answer 1

The join() method takes in an iterable as an argument (in you case, the list), and joins it with the string that you called it on (ie, an empty string or a space). So in your case, you can use:

' '.join(list) # 'Num1 Num2 Num3'

Also, list is a bad variable name since it eclipses the built in function list() .

Answer 2

list_sum = 0
for entry in list:
      list_sum += int(entry)
list_average = list_sum / len(list)

Something like that should work
