               Expense tracker is one of the important applications in Numpy. It tracks the daily expenses, calculates the highest, lowest, average and total expenses. Let us implement the expense tracker in numpy. Implementation: First, built-in numpy library is included. It creates an array to read the input from the user. Print the array of elements. Next, total expenses are calculated by adding all elements in the array using sum() function. To find the ‘Average’ value by using mean() function in the numpy package. Other functions are included as follows. ‘max()’: it gives you the maximum value. ‘min()’: it finds the minimum value. It also checks the expense value is greater than 150 and calculates the sum and prints it. Code: import numpy as np1 # Let us create daily expenses s_expenses = np1.array(list(map(int, input("Enter the weekly expenses separated by space: ").split()))) print("Expenses of the week:", s_ex...

                 If you want analyse the weather, then this is program. It uses the real world datasets with arrays. It combines indexing, masking to perform the process. Let us create a python program to implement weather data analysis. Implementation: It starts from including numpy object. Temperature data is collected from the user for a week. The average temperature for a week is calculated and printed. Next, minimum and maximum temperature is calculated using built-in functions. Hot days, cool days, rainy days are categorised by the temperature. Standard deviation is also calculated. Finally the weather report is displayed to the screen. Code: import numpy as np1 #Get the temperature inputs from the user temp = np1.array(list(map(int, input("Enter the weekly temperature separated by space: ").split()))) print("Temperature of the week",temp) #Average temperature,minimum,maximum temperature   calculation ...

#Mini Project 1: Student Mark Analyzer Create a Numpy Project to implements Student Marks Analysis. It creates a set of students as array. It includes the students name and marks. Find the average, minimum and maximum marks. Print the values. Check for passed students, failed students and distinction students. If the mark is greater than 40, then the student passed the exam. Otherwise, the student failed in the exam. For finding the distinction, check the mark is greater than 75. Finally, print the results. Let us print the grade based on the marks. If the mark is greater than or equal to 90, grade is ‘A+’. Else, if the mark is greater than or equal to 75,then the grade is ‘A’. Else if, the mark is greater than 60,the grade is ‘B’. else if the mark is less than 40, the student’s grade is ‘C’ and ‘F’. Finally, print the grade. Complete Program import numpy as np1 # Student data creation students = np1.array([     "Ajay",     "Bob", ...

  What is Aggregation?               It combines the multiple values together and forms a single value. The value depends on the operation. Let us implement some aggregate functions in numpy using python. Implementation:               This program includes the numpy object. It creates an array of elements. It has following functions to provide aggregate functions. Sum : adds all elements together. Mean: finds the mean value. Median: finds the middle highest value. Min: it gives you the minimum value. Max: it gives you the maximum value. Std: it calculates the standard deviation. Argmin: it displays index of minimum value. Argmax: it gives you the index of maximum value. Code: import numpy as np1 s_arr = np1.array([11,12,13,14,15,16,17]) print("The original array is:",s_arr) a_sum = np1.sum(s_arr) a_mean=np1.mean(s_ar...

               This is a branch of mathematics. It collects the data, analyses it and present it accordingly. It has many methods which is used to find sum, average, minimum , maximum and so on. Let us implement the list of functions given below….. Sum: to find the total of all elements. Mean: it find the average value. Median :it gives you the middle value after sorting. Maximum :this function gives you maximum value of the array. Minimum: it provides the minimum value of the array. Standard deviation: it finds the standard deviation value. Variance: it is the square of the standard deviation. Product: it multiplies all elements. Cumulative sum: it gives the running total. Cumulative product: it finds the running product value. Program to find values for all functions: import numpy as np1 s_arr = np1.array([11,12,13,14,15,16]) s_sum= np1.sum(s_arr) s_prod = np1.prod(s_arr) s_mean = np1.mean(s_arr) s_medi = np1....

                              It is one of the advanced indexing methods in Numpy. It makes you to find arbitrary elements in the list or array of index. Let us implement in different ways. ·        1D array ·        Reordering the elements of 1D array ·        2D array ·        Selecting specific elements 👉1D array:               This deals with Single dimensional array. First, it reads the array elements. Find the arbitrary elements. Finally, print the output. Code: import numpy as np1 s_arr = np1.array([11, 22, 33, 44, 55, 66, 77]) indices = [0, 2, 4] result = s_arr[indices] print("The indices are:",result) Output: The indices are: [11 33 55] 👉 Reordering the elements of 1D array:   ...
