.join() is a string method that concatenates the elements of an iterable (like a list or tuple) into a single string, placing the calling string between each element.
Syntax:
'separator'.join(iterable)Examples:
# Join with Comma
items = ['apple', 'banana', 'mango']
separator = ', '
combined = separator.join(items)
print(combined)
# output
# apple, banana, mango
# Join characters of a string:
word = 'Python'
separator = '-'
new_word = separator.join(word)
print(new_word)
# output
# P-y-t-h-o-n
# Join numbers (after converting to string):
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
separator = ' + '
join_numbers = separator.join((str(n) for n in numbers))
print(join_numbers)
# output
# 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10
