How to Split a String using delimiter in Python


There are multiple ways in which we can split a string in Python based on the delimiter, let's take a look at some of them with examples.


Example 1: Using the split() function

>>> string_data = "1,2,3,4,5,6,7,8,9,10"
>>> splitted_string = string_data.split(",")
>>> print(splitted_string)
['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
>>> 
>>> print(type(splitted_string))
<class 'list'>
>>> 

The most common delimiters that one comes across when parsing data line by line as strings in files are,

DelimiterSymbolDescription
Comma,Used to separate values in CSV files
Tab\tUsed as a delimiter in TSV files
Pipe|Commonly used in data interchange formats
Semicolon;Often used in European CSV files
Colon:Used in some data formats and configurations
SpaceSeparates values in space-delimited files
Hyphen-Used in certain data representations
Underscore_Occasionally used as a separator
Dot.Used in some file extensions

You can simply use the symbol like these as an argument to the split function.



Let's take another example where data is separated by pipe as a delimiter.

Example:
>>> string_data = "1|2|3|4|5|6|7|8|9|10"
>>> splitted_string = string_data.split("|")
>>> print(splitted_string)

['1', '2', '3', '4', '5', '6', '7', '8', '9', '10']
