Learn Python from Scratch

1. The basics

Hello, World!Hello, me!Variables Comments Indentation Numbers and strings

2. Arithmetic operations

Addition Multiplication and power Division and whole part division

3. Common data types

Data types Numbers float and int Storing text Strings slicing Concatenation

4. Conditional statements

Boolean data type Combining conditions Simple if/else expressions (1/2)Simple if/else expressions (2/2)If/else expressions with multiple conditions (1/2)If/else expressions with multiple conditions (2/2)

5. Other data types

Lists (1/3)Lists (2/3)Lists (3/3)Tuples (1/3)Tuples (2/3)Tuples (3/3)Dictionaries (1/2)Dictionaries (2/2)

6. Loops

while loop (1/2)while loop (2/2)for loop (1/5)for loop (2/5)for loop (3/5)for loop (4/5)for loop (5/5)

7. Functions

Built-in functions Writing your own functions (1/5)Writing your own functions (2/5)Writing your own functions (3/5)Writing your own functions (4/5)Writing your own functions (5/5)lambda functions

Numbers and strings

Python variables can store data of various allowed types. Some of the simplest data types are strings and integers (official names in Python are "str" and "int").

You can print the data type of a variable by using type() function (see example below):


              1234
            
#Example of a string variable
var = "42"
print(var)
print(type(var))

In the example above Python will print "42" and will treat this variable as a string.

In the example below it will also print "42", but will treat the variable as integer. You can only apply arithmetic operations to Numeric types (integer or others), not strings.


              1234
            
#Example of an integer variable
var = 42
print(var)
print(type(var))
