Answer:
Following are the correct python code to this question:
n1 = float(input('Input first number: '))#input first number  
n2 = float(input('Input second number: '))#input second number  
n3 = float(input('Input third number: '))#input third number  
n4 = float(input('Input fourth number: '))#input fourth number  
average = (n1+n2+n3+n4)/4 #calculate input number average
product = n1*n2*n3*n4 # calculate input number product
print('product: {:.0f}  average: {:.0f}'.format(round(product),round(average))) #print product and average using round function
print('product: {:.3f}  average: {:.3f}'.format(product,average)) #print product and average value
Output:

Explanation:
The description of the above python code can be defined as follows:
- In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
- In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
- In the last line, the print method is used, which prints its variable value by using a round and format method.

Answer:
b=0
c=0
lol=list()
while True:
    salary=input("Enter your salary: ")
    if salary=="e" or salary=="E":
        print("Thankyou!!")
        break
    else:
        a=int(salary)
        if a>=300000 and a<=400000:
             c=c+1
        if a<0 or a>400000:
            print("Your salary is either too small or too big ")
        if a>0 and a<=400000:
            a=a-(25/100*a)-(5/100*a)-(2/100*a)
            lol.append(a)
            b=b+1
            if a>=300000:
                 c=c+1
print(lol)
print("The number of salaries entered is: "+ str(b))
print("The number of salaries that exceeded 300000 is: "+str(c))
