String manipulation is a crucial skill in Python programming. The method breaks strings into lists, while combines list elements into strings. These tools are invaluable for parsing and formatting text data efficiently.
Mastering string and enhances your ability to work with textual information. Whether you're processing user input, handling data files, or generating formatted output, these techniques form the foundation of text manipulation in Python.
string.split([separator](https://www.fiveableKeyTerm:Separator), [maxsplit](https://www.fiveableKeyTerm:maxsplit))
separator
specifies the delimiter (default is whitespace)maxsplit
specifies the maximum number of splits to perform (optional)text = "Hello, world! How are you?" substrings = text.split() print(substrings) # Output: ['Hello,', 'world!', 'How', 'are', 'you?']
delimiter.join(list)
words = ['Hello', 'world', 'How', 'are', 'you?'] sentence = ' '.join(words) print(sentence) # Output: 'Hello world How are you?'
split()
allows specifying a custom delimiter instead of the default whitespace
csv_data = "John,Doe,25,New York" fields = csv_data.split(',') print(fields) # Output: ['John', 'Doe', '25', 'New York']
join()
allows specifying any delimiter string to join the list elements
tags = ['python', 'programming', 'tutorial'] tag_string = '-'.join(tags) print(tag_string) # Output: 'python-programming-tutorial'
