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)
```

Enter the Total Number of List Elements: 6

Enter the Value of 1 Element: -8

Enter the Value of 2 Element: -3

Enter the Value of 3 Element: 5

Enter the Value of 4 Element: 4

Enter the Value of 5 Element: -6

Enter the Value of 6 Element: 2

List Entered By the User: [-8, -3, 5, 4, -6, 2]

Total Number of Positive Numbers in this List = 3

Total Number of Negative Numbers in this List = 3

```
# Python Program to Count the Positive and Negative Numbers in a List Using While Loop

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)
while(j < Number):
if(NumList[j] >= 0):
Positive_count = Positive_count + 1
else:
Negative_count = Negative_count + 1
j = j + 1
print("\nTotal Number of Positive Numbers in this List = ", Positive_count)
print("Total Number of Negative Numbers in this List = ", Negative_count)
```

Enter the Total Number of List Elements: 6

Enter the Value of 1 Element: -8

Enter the Value of 2 Element: 6

Enter the Value of 3 Element: 4

Enter the Value of 4 Element: 6

Enter the Value of 5 Element: 3

Enter the Value of 6 Element: 2

List Entered By the User: [-8, 6, 4, 6, 3, 2]
