String Methods
- String methods in Python are built-in functions that allow you to manipulate and work with text data easily. Since strings are one of the most commonly used data types, understanding string methods is essential for every Python programmer.
String Methods in Python
upper() and lower()
upper() converts all characters in a string to uppercase.
lower() converts all characters in a string to lowercase.
Converting String Case
This example converts a string into uppercase and lowercase.
text = "Python Programming"
print(text.upper())
print(text.lower())
strip()
The strip() method removes extra spaces from the beginning and end of a string.
Removing Extra Spaces
This example removes leading and trailing spaces from a string.
text = " Python "
print(text.strip())
replace()
The replace() method replaces a word or character with another value.
Replacing Text in a String
This example replaces a word in the string.
text = "I like Java"
print(text.replace("Java", "Python"))split()
The split() method splits a string into a list based on a separator.
Splitting a String
This example splits a sentence into words.
text = "Python is easy"
print(text.split())
join()
The join() method joins elements of a list into a single string.
Joining List into String
This example joins list items using a space.
words = ["Python", "is", "fun"]
print(" ".join(words))
find()
The find() method returns the index of the first occurrence of a value.
Returns -1 if the value is not found.
Finding Text Position
This example finds the position of a word in a string.
text = "Learn Python"
print(text.find("Python"))
count()
The count() method counts how many times a value appears in a string.
Counting Occurrences
This example counts how many times a character appears.
text = "banana"
print(text.count("a"))
Escape Characters (\n, \t, etc.)
Escape characters are used to format text inside strings.
print("Python\nProgramming")
print("Python\tProgramming")
