can someone help me correct with this Spyder python. I don't know where do I get wrong

Assume that someone has collected a set of measurements and wants some statistical data about them. Write a program that asks a user for measurements and prints the average, the maximum, and the minimum measurement. Users should enter data elements one at a time from the keyboard. All data elements should be positive numbers. The user should be allowed to enter as many measurements as they want and should signify the end of the list by entering a negative value. The negative value should not be processed as part of the data set - it simply indicates that the user has finished entering measurements. Note: Do not use any containers (e.g. list/tuple/array) to store the measurements. Do not use the built-in statistics functions min(), max(). You should implement a loop and do data input/analysis inside the loop. print("Enter numbers: ",1,3,5,4,6) num = float(input()) maxVal = num minVal = num total = num count = 1 while(num > 0): num = float(input()). if(num num): minVal = num total += num print("Maximum =",maxVal) print("Miniimum =",minval) print("Average =",(total/count))||
