Study Notes
Strings in Python
- A string is a sequence of characters, which can be alphabets, numbers, special characters, or any other writable characters.
- Strings can be defined using single quotes or double quotes.
- A single-line string is a string that contains only one line, and it can be as long as desired.
- Multi-line strings are defined using three single quotes or three double quotes at the start and end, and can contain multiple lines of text.
Declaring and Printing Strings
- A string can be declared by assigning a value to a variable using single quotes or double quotes.
- The
print()
function is used to print a string.
String Functions
- The
len()
function is used to determine the length of a string, i.e., the number of characters it contains. - The
in
keyword is used to check if a certain character or string exists within another string. - The
type()
function can be used to determine the data type of a variable, which can be a Boolean (bool
) if it's used to check the presence of a string.
Slicing Strings
- Slicing is a method to carve out specific portions of a string.
- The syntax for slicing is
string_variable[starting_point:ending_point]
. - If the starting point is not specified, it defaults to 0.
- Slicing can be used on both string variables and string literals.
Modifying Strings
- The
upper()
function is used to convert a string to uppercase. - The
lower()
function is used to convert a string to lowercase. - The
strip()
function is used to remove spaces from the beginning and end of a string. - The
format()
function is used to format strings with placeholders.
Other String Functions
- There are many other functions available for strings, which will be covered in further documentation and exercises.
