How to find the maximum and minimum value in NumPy 1d-array? Last Updated : 15 Jul, 2025 Comments Improve Suggest changes Like Article Like Report Let's see the various ways to find the maximum and minimum value in NumPy 1d-array. Method 1: Using numpy.amax() and numpy.amin() functions of NumPy library. numpy.amax(): This function returns maximum of an array or maximum along axis(if mentioned). numpy.amin(): This function returns minimum of an array or minimum along axis(if mentioned). Example: Python3 # import library import numpy as np # create a numpy 1d-array array = np.array([1, 2, 3, 0, -1, -2]) # find max element in an array max_ele = np.amax(array) # find min element in an array min_ele = np.amin(array) # show the outputs print("Given Array:", array) print("Max Element:", max_ele) print("Min Element:", min_ele) Output: Given Array: [ 1 2 3 0 -1 -2] Max Element: 3 Min Element: -2 Method 2: Using numpy.argmax() and numpy.argmin() function of NumPy library. numpy.argmax(): This function returns indices of the max element of the array in a particular axis(if mentioned).numpy.argmin(): This function returns indices of the min element of the array in a particular axis(if mentioned). Example: Python3 # import library import numpy as np # create a numpy 1d-array array = np.array([1, 2, 3, 0, -1, -2]) # find index of max element # in an array max_ele_index = np.argmax(array) # find max element in an array max_ele = array[max_ele_index] # find index of min element # in an array min_ele_index = np.argmin(array) # find min element in an array min_ele = array[min_ele_index] # show the outputs print("Given Array:", array) print("Max Element:", max_ele) print("Min Element:", min_ele) Output: Given Array: [ 1 2 3 0 -1 -2] Max Element: 3 Min Element: -2 Create Quiz Comment A ankthon Follow 0 Improve A ankthon Follow 0 Improve Article Tags : Python Python-numpy Python numpy-program Python numpy-arrayManipulation Explore Python FundamentalsPython Introduction 2 min read Input and Output in Python 4 min read Python Variables 4 min read Python Operators 4 min read Python Keywords 2 min read Python Data Types 8 min read Conditional Statements in Python 3 min read Loops in Python - For, While and Nested Loops 5 min read Python Functions 5 min read Recursion in Python 4 min read Python Lambda Functions 5 min read Python Data StructuresPython String 5 min read Python Lists 4 min read Python Tuples 4 min read Python Dictionary 3 min read Python Sets 6 min read Python Arrays 7 min read List Comprehension in Python 4 min read Advanced PythonPython OOP Concepts 11 min read Python Exception Handling 5 min read File Handling in Python 4 min read Python Database Tutorial 4 min read Python MongoDB Tutorial 3 min read Python MySQL 9 min read Python Packages 10 min read Python Modules 3 min read Python DSA Libraries 15 min read List of Python GUI Library and Packages 3 min read Data Science with PythonNumPy Tutorial - Python Library 3 min read Pandas Tutorial 4 min read Matplotlib Tutorial 5 min read Python Seaborn Tutorial 3 min read StatsModel Library - Tutorial 3 min read Learning Model Building in Scikit-learn 6 min read TensorFlow Tutorial 2 min read PyTorch Tutorial 6 min read Web Development with PythonFlask Tutorial 8 min read Django Tutorial | Learn Django Framework 7 min read Django ORM - Inserting, Updating & Deleting Data 4 min read Templating With Jinja2 in Flask 6 min read Django Templates 5 min read Build a REST API using Flask - Python 3 min read Building a Simple API with Django REST Framework 3 min read Python PracticePython Quiz 1 min read Python Coding Practice 1 min read Python Interview Questions and Answers 15+ min read Like
