Python Greater Than or Equal To (>=) Operator

Python Greater Than or Equal To Operator

Python Greater than or Equal to operator is used to compare if an operand is greater than or equal to other operand.

The syntax of greater than or equal to comparison operator is

operand_1 ><= operand_2
Run this program

Greater than or Equal to operator returns a boolean value. True if operand_1 is greater than or equal to operand_2 in value. Otherwise, it returns False. If the operands are sequences like strings, lists, tuple, etc., corresponding elements of the objects are compared to compute the result.

For sequences, the comparison happens for all the respective elements from two sequences, until they get False from a comparison or the end of a sequence is reached with all Trues returned during comparisons.

Greater than or Equal to can be considered as a compound expression formed by Greater than operator and Equal to operator as shown below.

(operand_1 > operand_2) or (operand_1 == operand_2)

Example 1: Greater than or Equal to Operator

In this example, we will compare two integers, x and y, and check if x is greater than or equal to y.

Python Program

x = 57
y = 12
result = x >= y
print(result) #True

x = 8
y = 8
result = x >= y
print(result) #True

x = 78
y = 89
result = x >= y
print(result) #False
Run this program

Output

True
True
False

Example 2: Greater than or Equal to Operator with Sequences

Sequence could be a string, a list, a tuple, etc. You can compare two sequences using greater than or equal to comparison operator.

For numbers, it is straight forward mathematical decision if the left operand is greater than or equal to the right operand. But for sequences, the operator iteratively compares the respective elements from the two sequences. The comparison happens for all the respective elements from two sequences, until they get False from a comparison or the end of a sequence is reached with all Trues returned during comparisons.

In the following program, we will compare two lists, x and y, and check if x is greater than or equal to y.

Python Program

x = [41, 54, 21]
y = [9, 8]
z = [41, 54, 74, 6]
k = [41, 54, 21]
print(x >= y) #True
print(x >= z) #False
print(x >= k) #True
Run this program

Output

True
False
True

Checking x >= y means checking if [41, 54, 21] >= [9, 8]. During the comparison of first element in the lists, greater than or equal to operator returns True.

For x >= z means checking if [41, 54, 21] >= [41, 54, 74, 6]. During the comparison of first two element in the lists, greater than or equal to operator returns True. So, the operator investigates until it reaches the end of a list with True for all the elements, or a False in the mid way. For the third element, the operator returns False. The operator now stops the comparison and returns False for the overall comparison of two lists.

And for x >= k , from the data, it is straight forward that the operator returns True.
