Python: STRING .join() & .split()

.join() and .split() are two string methods in Python that are used for joining and splitting strings, respectively.

.join() Method:

• The .join() method is used to concatenate elements from an iterable (e.g., a list, tuple, or string) into a single string, using the calling string as the separator.
• Syntax: "separator".join(iterable)
• Example:

# Joining a list of words into a single string with space as separator 
words = ["Hello", "world", "Python"] 
sentence = " ".join(words) 
print(sentence) 
 
# Output: "Hello world Python"  

# Joining a list of numbers into a single string with a comma as separator 
numbers = [1, 2, 3, 4, 5] 
num_str = ",".join(map(str, numbers)) 
print(num_str)  
# Output: "1,2,3,4,5"

.split() Method:

• The .split() method is used to split a string into a list of substrings based on a specified delimiter. If no delimiter is provided, it splits the string on whitespace.
• Syntax: string.split(delimiter)
• Example:

# Splitting a string into a list of words (default delimiter is whitespace) 
text = "Hello world Python" 
words = text.split() 
print(words)  
# Output: ['Hello', 'world', 'Python']
