How to Assign integers to variables and subtraction:
The equal sign (=) is used to assign variables in python. The negative sign (-) is used for subtraction and type() is used to get the type of the variable. The type of is int in the case below. For example:
How to Assign floating point numbers to variables and addition:
The positive sign (+) is used for addition
Examples of adding and subtracting float and int:
Division of int:
Floating point division uses (/) sign. This type of division divides left hand operand by right hand operand and returns a floating point number. Floor Division uses (//) sign. This type of division is returns only the whole int part of division without any rounding. The modulus (%) operand returns the remainder.
Division of float:
Division of float returns only type float and everything else is the same as above.
Multiply int and float:
The multiply operand is (*). If the type is only int it returns int. If either type is float it returns a float.
Exponent of int and float:
The exponent operand is ( **). If the type is only int it returns int. If either type is float it returns a float.
How to assign strings and concatenate strings:
To assign variables to strings inclose strings with (' ') or (" "). As you can see below strings can be concatenated by the plus sign (+) and if you need a space between the words it needs to be added in. The type of strings is str.
Variable name guide lines:
For python style use lower_case_with_underscores for variable names. The words are separated by underscores to improve readability.
Variable names can not start with a number
