In a dictionary we can only test for presence of key, not the value. They are used to test whether a value or variable is found in a sequence ( string, list, tuple, set and dictionary). In and not in are the membership operators in Python. It is because the interpreter locates them separately in memory although they are equal. Same is the case with x2 and y2 (strings).īut x3 and 圓 are lists. Here, we see that x1 and y1 are integers of the same values, so they are equal as well as identical. True if the operands are not identical (do not refer to the same object)Įxample 4: Identity operators in Python x1 = 5 True if the operands are identical (refer to the same object) Two variables that are equal does not imply that they are identical. They are used to check if two values (or variables) are located on the same part of the memory. Is and is not are the identity operators in Python. Python language offers some special types of operators like the identity operator or the membership operator. In the table below: Let x = 10 ( 0000 1010 in binary) and y = 4 ( 0000 0100 in binary) Operator They operate bit by bit, hence the name.įor example, 2 is 10 in binary and 7 is 111. Here is the truth table for these operators.īitwise operators act on operands as if they were strings of binary digits. True if operand is false (complements the operand)Įxample 3: Logical Operators in Python x = True Logical operators are the and, or, not operators.

Greater than or equal to - True if left operand is greater than or equal to the right Greater than - True if left operand is greater than the right It returns either True or False according to the condition. Modulus - remainder of the division of left operand by the rightįloor division - division that results into whole number adjusted to the left in the number lineĮxponent - left operand raised to the power of rightĮxample 1: Arithmetic operators in Python x = 15Ĭomparison operators are used to compare values. Subtract right operand from the left or unary minusĭivide left operand by the right one (always results into float) 2 and 3 are the operands and 5 is the output of the operation.Īrithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication, etc. Here, + is the operator that performs addition. The value that the operator operates on is called the operand. Operators are special symbols in Python that carry out arithmetic or logical computation.
