bookData Types in Python

Python offers various data types, each serving a specific purpose and stored uniquely in memory for efficient coding. There's no need to memorize all of them. Use print(type(value)) to check a variable's type and experiment with different values to see their types.

# Text text_var = "Hello, World!" # `str` # Numeric int_var = 42 # `int` float_var = 3.14 # `float` complex_var = 2 + 3j # `complex` # Boolean bool_var = True # `bool` # Check variable type print(type(text_var))
copy

To switch between types, you can use int() for integers, float() for decimals, and complex() for complex numbers. However, be cautious when transforming one type to another.

# Variables int_num = 11 real_num = 16.83 # Displaying original and converted numbers (integer - to float, and vice versa) # Converting a decimal to an integer drops the decimal without rounding. print(int_num, float(int_num)) print(real_num, int(real_num))
copy

Dividing two integers with the / operator always returns a float, even if the division is exact. To perform integer division and get the quotient without the remainder, use the // operator.

# Perform division of two integers division = 25 / 5 # The result of the division and its type print(division, type(division))
