Introduction to String Methods in Python

Strings are a fundamental data type in Python, and
there are various methods available to manipulate and
process strings. In this video, we will cover the most
common string methods, including the capitalize
method, the lower method, the upper method, the
isdigit method, the isalpha method, the count method,
the replace method, and more.

Capitalization

The capitalize method is used to convert a string to
uppercase, except for the first character, which is
capitalized. For example, lets create a string variable
called name and assign it the value hello. We can use
the capitalize method to convert the string to
uppercase, except for the first character.

Lowercase

The lower method is used to convert a string to
lowercase. For example, lets create a string variable
called name and assign it the value Hello. We can use
the lower method to convert the string to lowercase.

Uppercase

The upper method is used to convert a string to
uppercase. For example, lets create a string variable
called name and assign it the value hello. We can use
the upper method to convert the string to uppercase.

Digit Check

The isdigit method is used to check if a string contains
only digits. For example, lets create a string variable
called num and assign it the value 1234. We can use the
isdigit method to check if the string contains only digits.
