In this python program, we will learn how to count the positive and negative numbers in a given list. In this program, we will identify the positive and negative numbers and display the total number of positive and negative numbers in a given list.
Here is the source code of the program to count the positive and negative numbers in a list.
# Python Program to Count the Positive and Negative Numbers in a List Using For Loop
NumList = []
Positive_count = 0
Negative_count = 0
# Take the Input From the User
Number = int(input("Enter the Total Number of List Elements: "))
for i in range(1, Number + 1):
value = int(input("Enter the Value of %d Element: " %i))
NumList.append(value)
# Print the List Entered by the User
print("\nList Entered By the User: ",NumList)
for j in range(Number):
if(NumList[j] >= 0):
Positive_count = Positive_count + 1
else:
Negative_count = Negative_count + 1
print("\nTotal Number of Positive Numbers in this List = ", Positive_count)
print("Total Number of Negative Numbers in this List = ", Negative_count)
