Split a string containing multiple lines of text using Python's splitlines() function

Use Python's splitlines() function to split a string containing multiple lines of text

In Python, strings are one of the frequently used data types. In actual development, we sometimes need to operate on strings containing multiple lines of text. At this point, we can use the splitlines() function to split multiple lines of text in the string to facilitate processing of each line. This article will explain how to use the splitlines() function through specific code examples.

1. The basic syntax of the splitlines() function

The basic syntax of the splitlines() function is as follows:

string.splitlines([keepends])

Among them, string is the string to be split, and keepends is an optional parameter indicating whether to retain the line terminator in the string. By default, the value of keepends is False, that is, the line terminator, "
" or "
" is not retained.

2. Split a string using the splitlines() function

Now, let’s see how to split a string containing multiple lines of text using the splitlines() function.

First, we define a string containing multiple lines of text. The example is as follows:

text = 'Python is a popular programming language.
It is widely used in data analysis and web development.
'

Then, we can use the splitlines() function to split multiple lines of text in the string, the code is as follows:

lines = text.splitlines()

The above code splits the multiple lines of text in the text string into a list of lines. We can use a for loop to iterate through the list to process each line, an example is as follows:

for line in lines:

print(line)

The output is as follows:

Python is a popular programming language.
It is widely used in data analysis and web development.

3. Preserve line terminators

Sometimes, we need to preserve the line terminators line terminator, so how to operate?

We can retain the line terminators by passing a True parameter to the splitlines() function. The example is as follows:

lines = text.splitlines(True)

In the above code , we passed a True parameter, which means to preserve the line terminators in the string. Now, we can use a for loop to iterate through the list, as shown below:

for line in lines:

print(line)

The output will look like this:

Python is a popular programming language .

It is widely used in data analysis and web development.

As you can see, the line terminator of each line is retained in the output result.

4. Split a string containing multiple line terminators

Sometimes, a string contains multiple different line terminators, such as "
", "", "
", etc. At this time, we can still use the splitlines() function to split it.

For example, we define a string text that contains a variety of line terminators. The example is as follows:

text = 'Python is a popular programming language.
It is widely used in data analysis and web development.
'

Now, we can directly use the splitlines() function to split, the code is as follows:

lines = text.splitlines()

The above code splits various line terminators in the text string as delimiters.

5. Conclusion

This article introduces the method of using the splitlines() function in Python to split a string containing multiple lines of text, and explains it through specific code examples. . In actual development, we can process each split line as needed to achieve the corresponding purpose.
