The ‘join()‘ method in Python can be used to concatenate items of an iterable (such as a list, tuple or string) into a single string:
1. To join the items of a list of strings into a single string:
my_list = ["apple", "grape", "mango", "peach", "lemon"]
my_string = ", ".join(my_list)
print(my_string)
print(type(my_string))
The result:
apple, grape, mango, peach, lemon
<class 'str'>2. To join the items of a list of numbers into a single string:
my_list = [1, 2, 3, 4, 5]
my_string = "".join([str(i) for i in my_list])
print(my_string)
print(type(my_string))
The result:
12345
<class 'str'>3. To join the items of a tuple into a single string:
my_tuple = ("apple", "grape", "mango", "peach", "lemon")
my_string = " | ".join(my_tuple)
print(my_string)
print(type(my_string))
The result
apple | grape | mango | peach | lemon
<class 'str'>4. To join the characters of a string into a single string:
string_example = "Hello"
my_string = "-".join(string_example)
print(my_string)
print(type(my_string))
The result:
H-e-l-l-o
<class 'str'>
