Find Maximum of two numbers in Python

Given two numbers, write a Python code to find the Maximum of these two numbers.

Examples:

Input: a = 2, b = 4
Output: 4

Input: a = -1, b = -4
Output: -1

Find Maximum of two numbers in Python

This is the naive approach where we will compare two numbers using if-else statement and will print the output accordingly.

Example:

Python3

# Python program to find the
# maximum of two numbers


def maximum(a, b):

    if a >= b:
        return a
    else:
        return b

# Driver code
a = 2
b = 4
print(maximum(a, b))

Output

4

Time complexity: O(1)
Auxiliary space: O(1)

Find Maximum of two numbers Using max() function

This function is used to find the maximum of the values passed as its arguments.

Example:

Python3

# Python program to find the
# maximum of two numbers


a = 2
b = 4

maximum = max(a, b)
print(maximum)

Output

4

Time complexity: O(1)
Auxiliary space: O(1)

Maximum of two numbers Using Ternary Operator

This operator is also known as conditional expression are operators that evaluate something based on a condition being true or false. It simply allows testing a condition in a single line

Example:

Python3

# Python program to find the
# maximum of two numbers

# Driver code
a = 2
b = 4

# Use of ternary operator
print(a if a >= b else b)

Output

4

Time complexity: O(1)
Auxiliary space: O(1)

Maximum of two numbers Using lambda function 

Python3

# python code to find maximum of two numbers

a=2;b=4
maximum = lambda a,b:a if a > b else b
print(f'{maximum(a,b)} is a maximum number')

Output:

4 is a maximum number

Maximum of two numbers Using list comprehension

Python3

a=2;b=4
x=[a if a>b else b]
print("maximum number is:",x)

Output

maximum number is: [4]

Maximum of two numbers Using sort() method

Python3

# Python program to find the
# maximum of two numbers
a = 2
b = 4
x=[a,b]
x.sort()
print(x[-1])

Output

4

Time Complexity : O(NlogN)
Auxiliary Space : O(1)
