The Quick and Easy Way to Analyze Numpy Arrays

Image
The quickest and easiest way to analyze NumPy arrays is by using the numpy.array() method. This method allows you to quickly and easily analyze the values contained in a numpy array. This method can also be used to find the sum, mean, standard deviation, max, min, and other useful analysis of the value contained within a numpy array. Sum You can find the sum of Numpy arrays using the np.sum() function.  For example:  import numpy as np  a = np.array([1,2,3,4,5])  b = np.array([6,7,8,9,10])  result = np.sum([a,b])  print(result)  # Output will be 55 Mean You can find the mean of a Numpy array using the np.mean() function. This function takes in an array as an argument and returns the mean of all the values in the array.  For example, the mean of a Numpy array of [1,2,3,4,5] would be  result = np.mean([1,2,3,4,5])  print(result)  #Output: 3.0 Standard Deviation To find the standard deviation of a Numpy array, you can use the NumPy std() function. This function takes in an array as a par

How to Find Max and Min Quickly in Python List

Here's logic to find Max and Min values in a List. Without using built-in Max() and Min () functions you can find Max and Min values in a List. For that matter, you need to write a user-defined function. This post is all about how to write it and run.

Finding Max and Min in List


You can achieve this by writing a user-defined function. Here's useful logic and steps to write it precisely.

You can write an user-defined function to get MAX and MIN values. In this function, I am using the max(), min() built-in functions. The other variables you can use as you wish. Below is the my actual logic.


Python Function to find Maximum and Minimum Easily


Sample Code

def findmaxmin(data): 
ax = max(data) 
by = min(data) 
return(x,y)
data = (109, 98, 88, 7) 
(maximum, minimum) = findmaxmin (data) 
print("Maximum Marks = ", maximum) 
print("Minimum Marks = ", minimum)


Created a Script Using vim editor

Here as the first step, I have written the maxmin.py file in Ubuntu. The function name is  "findmaxmin ".

define function using input arguments

Result


Below command to enter Python. This command, you can issue in Ubuntu where python3 is installed

$ python3

You have now entered Python3.

>>> import maxmin

You will prompt a message that imported successfully without any syntax errors.

Code in the Python Script


How to import python script and run


Below commands, I have issued.

>>> data = (109, 98, 88, 7)
>>> maxmin.findmaxmin(data)


The result is (109, 7)
