Python – The Basics of Strings
In Python, strings are surrounded by either single quotation marks, or double quotation marks. “Hello World” is the same as ‘Hello World’.
Python – Slicing Strings
A range of characters can be returned from a string by using the slice syntax.
Python – String Concatenation
To concatenate, or combine, two strings in Python, the + operator is used.
Python – Escaping Characters in a String
To insert characters that will cause problems in a string, an escape character (backslash \ followed by the character you want to insert) is used.
Python – Formatting Strings
To format a string, F-String is used by putting an f in front of the string literal and adding curly brackets {} as placeholders for variables/operations.
Python – Formatting Strings
There are two ways to format strings in Python: Using F-strings (the preferred way since v3.6) and the format() method (older and less efficient).
Python – String capitalize() Method
The Python string capitalize() method returns a string where the first character is upper case, and the rest is lower case.
Python – String casefold() Method
The Python string casefold() method returns a string where all the characters are lower case.
Python – String center() Method
The Python string center() method will center align the string, using a specified character (space is default) as the fill character.
Python – String count() Method
The Python string count() method returns the number of times a specified value appears in the string.
Python – String encode() Method
The Python string encode() method encodes the string using the specified encoding. If no encoding is specified, UTF-8 will be used.
Python – String endswith() Method
The Python string endswith() method returns “True” if the string ends with the specified value, and “False” if it does not.
Python – String expandtabs() Method
The Python string expandtabs() method sets the tab size to the specified number of whitespaces.
Python – String find() Method
The Python string find() method finds the first occurrence of the specified value, and returns -1 if the value is not found.
Python – String format() Method
The Python string format() method formats the specified value(s) and insert them inside the string’s placeholder and returns the formatted string.
Python – String index() Method
The Python string index() method finds the first occurrence of the specified value, and raises an exception if the value is not found.
Python – String isalnum() Method
The Python string isalnum() method returns True if all the characters are alphanumeric, meaning alphabet letter (a-z) and numbers (0-9).
Python – String isalpha() Method
The Python string isalpha() method returns True if all the characters are alphabet letters (a-z).
Python – String isascii() Method
The Python string isascii() method returns True if all the characters are ascii characters (a-z).
