Numbers in Python, as one of the main data types, are widely used in programming. Python naturally supports several different numeric formats including integers, floating-point numbers, or complex numbers. Each of these types of data has specific applications and unique features.
The integer variable type is designated for storing whole numbers without fractions. These variables can be positive, negative, or even zero and are usable throughout the program. However, if you need a number with a decimal point, you would use float.
The float data type, known for representing floating-point numbers, is used to store numbers with decimal points, allowing for the storage of more precise and larger values.
Additionally, there is another data type called complex used for storing mixed numbers containing a real and an imaginary part. This data type is mainly applied in advanced discussions such as science and engineering.
Example Code for Using Numbers in Python
# Defining an integer
number_integer = 42
# Defining a float
number_float = 3.14
# Defining a complex number
number_complex = 1 + 5j
# Performing simple operations
sum_integer = number_integer + 5
# Performing operations with floats
product_float = number_float * 2
Line Explanations
# Defining an integer This line defines an integer variable with the value 42.
# Defining a float This line creates a floating-point number named
number_float with the value 3.14.# Defining a complex number Here we define a complex number consisting of real and imaginary parts.
# Performing simple operations The integer variable is incremented by 5, and the result is stored in
sum_integer.# Performing operations with floats The value of
number_float is multiplied by 2, and the result is stored in product_float.
