Write a program in python that reads an unspecified number of integers from the user, determines how many positive and negative
blondinia [14]

Answer:

count_p = 0

count_n = 0

total = 0

while True:

   number = int(input("Enter an integer, the input ends if it is 0: "))

   if number == 0:

       break

   else:

       total += number

       if number > 0:

           count_p += 1

       elif number < 0:

           count_n += 1

print("The number of positives is: " + str(count_p))

print("The number of negatives is: " + str(count_n))

print("The total is: " + str(total))

print("The average is: " + str(total / (count_p + count_n)))

Explanation:

Initialize the variables, count_p represens the number of positives, count_n represents the number of negatives, and total represents the total of the numbers

Create a while loop iterates until the user enters 0. If the number is not 0, then add it to the total. If the number is greater than 0, increase count_p by 1. If the number is smaller than 0, increase count_n by 1.

When the loop is done, print the count_p, count_n, total, and average

Write a program that asks the user how many numbers will be entered and then has the user enter those numbers. When this is done
KATRIN_1 [288]

Answer:

<em>The program written in Python 3 is as follows;</em>

<em>The program does not make use of comments; however, see explanation section for detailed line by line explanation of the program</em>

num = int(input("Number of Inputs: "))

mylist = []

userinput = int(input("Enter a digit: "))

i = 1

while i < num:

     mylist.append(userinput)

     userinput = int(input("Enter a digit: "))

     i += 1

   

try:

     first7 = mylist.index(7)+1

     print('The first position of 7 is ',first7)

     last7 = num - 1 - mylist[::-1].index(7)

     print('The last position of 7 is ',last7)

except:

     print('7 is not on the list')

Explanation:

This line prompts user for the number of inputs

num = int(input("Number of Inputs: "))

This line declares an empty list

mylist = []

This line inputs the first number into the empty list

userinput = int(input("Enter a digit: "))

The italicized lines represent an iteration that allows user to input the numbers into the empty list.

<em>i = 1</em>

<em>while i < num:</em>

<em>      mylist.append(userinput)</em>

<em>      userinput = int(input("Enter a digit: "))</em>

<em>      i += 1</em>

The try-except is used to check the presence of 7 in the list

try:

This checks the first occurrence of 7

     first7 = mylist.index(7)+1

This prints the first occurrence of 7

     print('The first position of 7 is ',first7)

This checks the last occurrence of 7

     last7 = num - 1 - mylist[::-1].index(7)

This prints the last occurrence of 7

     print('The last position of 7 is ',last7)

The following is executed if there's no occurrence of 7

except:

     print('7 is not on the list')

Sometimes, fourth-generation languages (4GLs) are called procedural languages
irakobra [83]
Hi!

In 1981, the term 4GL was actually used to refer to languages which were <em>non-procedural. </em>A procedural language does not possess <em>object-oriented </em>capabilities. 4GL's often times have OOP properties, so I believe the answer to this question is going to be <em>false. </em>=)
