Split Multiple Characters from String in Python

Introduction:

In this tutorial we are learning about how to split multiple characters from string in Python. In Python, string is a simple data type used to store and manipulate text files. Splitting a string into multiple characters is a text-processing function in Python. From time to time, while coding or improving your programming skills, you must come across many situations in Python where you want to use the split() function to split multiple parameters simultaneously instead of a single character. In this article we will see different ways to split Python strings into multiple numbers. An example of splitting multiple characters from the string is given below -

In Python, we can easily split multiple characters from a string using different methods. Using these methods, it is very easy to split and replace single characters in strings in Python. The methods are given below -

1. Using the split() function
2. Using the replace() function
3. Using the re.split() function
4. Using the re.findall() function

Now we learn about these functions for splitting multiple characters from a string in Python, which are given below -

1. Using the split() function:

We are using the split() function in Python to split multiple characters from a string. Here, we iterate through each character and split the string using the split() function. After splitting the string, we concatenate the result with spaces using the join() function and split the modified string by whitespace to get the desired list of strings.

Program Code:

Here, we give the program code for splitting the multiple characters from a string using the split() in Python. The code is given below -

Output:

Now, we run the above code and find the result after splitting the multiple characters from a string in Python. The result is given below -

The given string is:  Hello everyone, welcome to javatpoint
After splitting the given string:  ['Hello', 'everyone', 'welcome', 'to', 'javatpoint']

2. Using the replace() function:

We are using the replace() function for splitting multiple characters from a string in Python. This is another method for splitting a string. It does not use regular expressions and does not make sufficient. If you know the characters you want to split, replace them with spaces and use the split() function.

Program Code:

Here, we give the program code for splitting the multiple characters from a string using the replace() in Python. The code is given below -

Output:

Now, we run the above code and find the result after splitting the multiple characters from a string in Python. The result is given below -

The given string is: Hello@everyone, welcome to javatpoint
The result after splitting the given string is: ['Hello', 'everyone', 'welcome', 'to', 'javatpoint']

3. Using the re.split() function:

We are using the re.split() function in Python to split multiple characters from a string. This is the most efficient and versatile way to split multiple characters at once. It does this using regular expressions or regex.

Program Code:

Here, we give the program code for splitting multiple characters from a string using the re.split() in Python. The code is given below -

Output:

Now, we run the above code and find the result after splitting the multiple characters from a string in Python. The result is given below -

The given string is: Hello@everyone, welcome_to-javatpoint
The result after splitting the given string is: ['Hello', 'everyone', 'welcome', 'to', 'javatpoint']

The line re.split(', |_|-|!|@', string) tells Python to split the data between the following characters: , or _ or _ or ! or @. The "|" symbol represents "or". Some characters are considered special characters in regular expressions and have different functions. If you want to split characters this way, you need to run it with "\" (backslash) and add a space before and after the special character.

List of some special characters to avoid before using:

Program Code:

Here, we give another program code for splitting the multiple characters from a string using the re.split() in Python. The code is given below -

Output:

Now, we run the above code and find the result after splitting the multiple characters from a string in Python. The result is given below -

The result after splitting the given string is:  ['Hello', 'everyone', 'welcome', 'to', 'javatpoint', ' good ', ' morning']
The result after splitting the given string is:  ['Hello', 'everyone', 'welcome', 'to', 'javatpoint', ' good', 'morning']

4. Using the re.findall() function:

We are using the re.findall() function for splitting multiple characters from a string in Python. This is a more mysterious form but saves time. It also uses regular expressions as above, but instead of using the .split() method, it uses a method called .findall(). This method finds all instances and returns all instances in the list. This split method is best used when you need to know the exact characters you want to split.

Program Code:

Here, we give a program code for splitting multiple characters from a string using the re.findall() in Python. The code is given below -

Output:

Now, we run the above code and find the result after splitting the multiple characters from a string in Python. The result is given below -

The given string is: This, is - a # example? of the findall-method!
The result after splitting the given string is: ['This', 'is', 'a', 'example', 'of', 'the', 'findall', 'method']

Here, the [\w']+ keyword means that it will find all instances of one or more letters or underscores (_) and return them in a list. Note: [\w']+ is not separated from the underscore (_) because it searches for letters and underscores.

Program Code:

Here, we give another program code for splitting the multiple characters from a string using the re.findall() in Python. The code is given below -

Output:

Now, we run the above code and find the result after splitting the multiple characters from a string in Python. The result is given below -

The result after splitting the given string is:  ['This', 'is', 'a', 'example', 'of', 'the', 'findall', 'method']

Conclusion:

In this tutorial, we learn how to split multiple characters from a string in Python. We learn four methods for splitting multiple characters from a given string, along with some suitable program code.
