This is a list that contains values. You can print the list. 

#!/usr/bin/python3
list = ["apple", "banana", "orange", "grapes"]
print(list)

Which should return the following.

['apple', 'banana', 'orange', 'grapes']

join can be used to convert the list to a string.

#!/usr/bin/python3
list = ["apple", "banana", "orange", "grapes"]
print(' '.join([x for x in fruits]))

Or more commonly, like this.

#!/usr/bin/python3
list = ["apple", "banana", "orange", "grapes"]

print(f"list = {list}")

list_to_string = ' '.join([elem for elem in list])

print(f"list_to_string = {list_to_string}")

Which should return the following.

list = ['apple', 'banana', 'orange', 'grapes']
list_to_string = apple banana orange grapes

Instead of using a single whitespace as the delimiter, you may want to instead use something like /r/n.

#!/usr/bin/python3
list = ["Hello World", "Goodbye World"]

print(f"list = {list}")

list_to_string = '/r/n'.join([elem for elem in list])

print(f"list_to_string = {list_to_string}")

Which should return the following.

list = ['Hello World', 'Goodbye World']
list_to_string = Hello World/r/nGoodbye World

Or, create a function to convert any list into a string.

list = ["apple", "banana", "orange", "grapes"]

def convert_list_to_string(list):
  return ' '.join([elem for elem in list])

list = convert_list_to_string(list )

Sometimes you may have a list that contains a string, perhaps something like this. join can be used to convert the list to a string.

#!/usr/bin/python

mylist   = ["this is my list"]
mystring = ''.join(mylist)

print(mystring)

Which should print the following.

this is my list
