 true, false and none are capitalized while the others are in lower case.

 spaces are not allowed in variable names.

 in is a keyword.

 in python, power operator is x**y i.e. 2**3=8.

 when both of the operands are integer then python chops out the fraction part and gives you the round off value, to get the accurate answer use floor division. this is floor division. for ex, 5/2 = 2.5 but both of the operands are integer so answer of this expression in python is 2. to get the 2.5 answer, use floor division.

 modulus operator gives the remainder. so, 22%3 gives the remainder, that is, 1.

 you can’t perform mathematical operation on string even if the string is in the form: ‘1234…’.

 first this expression will solve 1**3 because exponential has higher precedence than multiplication, so 1**3 = 1 and 3*1 = 3. final answer is 3.

 “addition and subtraction” are at the same precedence level. similarly, “multiplication and division” are at the same precedence level. however, multiplication and division operators are at a higher precedence level than addition and subtraction operators.

 // is the operator for truncation division. it is called so because it returns only the integer part of the quotient, truncating the decimal part. for example: 20//3 = 6.
