How to use Python’s join() function to merge strings

Overview:
In Python, we often encounter the need to merge multiple strings Condition. Python provides a very convenient method join() to merge strings. This article will introduce how to use the join() function and provide some specific code examples.

How to use the join() function:
The join() function is a method of string. It accepts an iterable object as a parameter and uses the specified string as the element in the object. separator to merge. In Python, strings, lists, and tuples are all iterable objects, so the join() function can be used to merge these types of data.

The syntax of the join() function is as follows:

"分隔符".join(可迭代对象)

Among them, "separator" is the string that serves as the separator for each element in the merged result, and the iterable object is the string to be merged , list or tuple.

Specific code examples:
The following are some specific code examples that use the join() function to merge strings.

1. Merge string list:

   strings = ['Hello', 'World', 'Python']
   result = ' '.join(strings)
   print(result)

   Output result:

   Hello World Python

2. Merge string tuple:

   strings = ('Hello', 'World', 'Python')
   result = ' '.join(strings)
   print(result)

   Output result:

   Hello World Python

3. Merge strings and numbers:

   strings = ['Hello', 'World']
   number = 2021
   result = '-'.join(strings + [str(number)])
   print(result)

   Output result:

   Hello-World-2021

4. Merge contains String list of spaces:

   strings = ['Hello', '', 'World', '', 'Python']
   result = ' '.join(strings)
   print(result)

   Output result:

   Hello  World  Python

Summary:
In Python, using the join() function can easily merge multiple For strings, you only need to put the strings to be merged into an iterable object and specify the delimiter between each element in the merged result. This article provides some specific code examples, hoping to help readers better understand and use the join() function. If there is anything unclear, please leave a message for discussion.
