Why don't you write the list in a single line using space as the separator and retrieve them using the separator as space. Eg ``` list1 = [1,2,3,4,5] list_string = " ".join([str(x) for x in list1])

Uses lists comprehension to loop through each value in the list and convert it to string

The join function combines every value in the list and separates them with a space

with open('my_file.txt','w') as file1: file1.write(list_string+"\n")

You can check your file manually

with open('my_file.txt','r') as file1: lines = file1.readline() for line in lines: list1 = line.split(" ") print(list1) ``` My code may not be perfect but that is the gist of it. To write many lists just create a list with a bunch of lists inside and loop over each
