Python String Methods

Python consists of built-in methods that will be used on the strings. They will manipulate the strings. However, the string method won’t change the original string instead it will return the new string along with the changed attributes. Let us look into this article to learn more about Python String Methods.

What is Python String?

Python string consists of the sequence of the Unicode characters that will be enclosed in the quotation marks. Hence, you can find Python string methods below.

What are the Python String Methods?

Python functions will change the case of the strings. Check out the Python String Methods provided below:

a. lower()-It will convert all the uppercase characters in a string to the lowercase.

b.upper(): This string method in Python will turn all the lowercase characters in a string into the uppercase.

c.title(): It will change the string to the title case.

d.swapcase(): It will swap the cases of all the characters in the string.

e.capitalize(): capitalize will convert the first character of the string to the uppercase.

List of Python String Methods

Let us look into the table below to learn more about the Python String Methods list.

What are the examples for changing the Cases of Python Strings?

Example

Let us look into the example provided below for changing the case of the Python string.

# Define a sample string
sample_string = "Hello, World!"

# 1. len(): Get the length of the string
length = len(sample_string)
print(f"Length of the string: {length}")

# 2. upper(): Convert the string to uppercase
uppercase_string = sample_string.upper()
print(f"Uppercase string: {uppercase_string}")

# 3. lower(): Convert the string to lowercase
lowercase_string = sample_string.lower()
print(f"Lowercase string: {lowercase_string}")

# 4. capitalize(): Capitalize the first character of the string
capitalized_string = sample_string.capitalize()
print(f"Capitalized string: {capitalized_string}")

# 5. count(): Count the occurrences of a substring in the string
substring_count = sample_string.count("l")
print(f"Count of 'l' in the string: {substring_count}")

# 6. replace(): Replace a substring with another substring
replaced_string = sample_string.replace("Hello", "Hi")
print(f"String after replacement: {replaced_string}")

# 7. split(): Split the string into a list of substrings based on a delimiter
split_string = sample_string.split(",")
print(f"String after split: {split_string}")

# 8. strip(): Remove leading and trailing whitespaces from the string
whitespace_string = "    Hello, World!    "
stripped_string = whitespace_string.strip()
print(f"String after stripping whitespaces: {stripped_string}")

Output

Length of the string: 13
Uppercase string: HELLO, WORLD!
Lowercase string: hello, world!
Capitalized string: Hello, world!
Count of 'l' in the string: 3
String after replacement: Hi, World!
String after split: ['Hello', ' World!']
String after stripping whitespaces: Hello, World!

Conclusion

To conclude, a Python string is a sequence of characters enclosed by quotation marks. This article has also listed the various Python string methods and will help the students to improve their knowledge and skills in Python String Methods.
