Python code to count positive negative and zero in a list

In this article, we will discuss the concept of Python code to count positive negative and zero in a list.

In this program, we are going to learn how to count Positive numbers, Negative numbers and zeros in a list using several ways in Python language.

This is done using for loop , while loop, and function in Python language

Count positive negative and zero in a list

Code to count positive negative and zero in a list using for loop

In this program, we will count positive number, negative number and zeros from given numbers in a list using a for loop in Python language

Program 1

#Python program to count positive, negative numbers in a list
Num_List=[]
positive_Count=0
negative_Count=0
zero_Count=0

num=int(input("Please enter the total number of elements in a list: "))
for i in range(1,num+1):
   val=int(input("Please enter the values of %d elements list: "%i))
   Num_List.append(val)

for j in range(num):
     if(Num_List[j]>0):
       positive_Count=positive_Count+1
     elif(Num_List[j]<0):
        negative_Count=negative_Count+1
     else:
      
       zero_Count=zero_Count+1
print("Total positive number in the list=",positive_Count)
print("Total negative number in the list=",negative_Count)
print("Total zeros in the list=",zero_Count)

When the above code is executed, it produces the following result

Please enter the total number of elements in a list: 8
Please enter the values of 1 elements list: 543
Please enter the values of 2 elements list: 785
Please enter the values of 3 elements list: 0
Please enter the values of 4 elements list: -524
Please enter the values of 5 elements list: -542
Please enter the values of 6 elements list: 567
Please enter the values of 7 elements list: 541
Please enter the values of 8 elements list: -67
Total positive number in the list= 4
Total negative number in the list= 3
Total zeros in the list= 1

Code to count positive negative and zero in a list using while loop

In this program, we will count positive number, negative number and zeros from given numbers in a a list using a while loop in Python language

Program 2

#Python program to count positive, negative numbers in a list
Num_List=[]
positive_Count=0
negative_Count=0
zero_Count=0
j=0

num=int(input("Please enter the total number of elements in a list: "))
for i in range(1,num+1):
   val=int(input("Please enter the values of %d elements list: "%i))
   Num_List.append(val)

while(j<num):
     if(Num_List[j]>0):
       positive_Count=positive_Count+1
     elif(Num_List[j]<0):
        negative_Count=negative_Count+1
     else:
       zero_Count=zero_Count+1
     j=j+1  
print("Total positive number in the list=",positive_Count)
print("Total negative number in the list=",negative_Count)
print("Total zeros in the list=",zero_Count)

When the above code is executed, it produces the following result

Please enter the total number of elements in a list: 10
Please enter the values of 1 elements list: 432
Please enter the values of 2 elements list: 0
Please enter the values of 3 elements list: -567
Please enter the values of 4 elements list: 321
Please enter the values of 5 elements list: -673
Please enter the values of 6 elements list: 0
Please enter the values of 7 elements list: 543
Please enter the values of 8 elements list: -865
Please enter the values of 9 elements list: 345
Please enter the values of 10 elements list: 678
Total positive number in the list= 5
Total negative number in the list= 3
Total zeros in the list= 2

Code to count positive negative and zero in a list using function

In this program, we will count positive number, negative number and zeros from given numbers in a list using a function in Python language

Program 3

#Python program to count positive, negative numbers in a list
def countPositive(Num_List):
 positive_Count=0
 for j in range(num):
   if(Num_List[j]>0):
       positive_Count=positive_Count+1
 return positive_Count

def countNegative(Num_List):
 negative_Count=0
 for j in range(num):
     if(Num_List[j]<0):
        negative_Count=negative_Count+1
 return negative_Count
    
def countZero(Num_List):
 zero_Count=0
 for j in range(num):
     if(Num_List[j]==0):
       zero_Count=zero_Count+1
 return zero_Count

Num_List=[]
num=int(input("Please enter the total number of elements in a list: "))
for i in range(1,num+1):

  val=int(input("Please enter the values of %d elements list: "%i))
  Num_List.append(val)
print("Total positive number in the list=",countPositive(Num_List))
print("Total negative number in the list=",countNegative(Num_List))
print("Total zeros in the list=",countZero(Num_List))

When the above code is executed, it produces the following result

Please enter the total number of elements in a list: 7
Please enter the values of 1 elements list: 67
Please enter the values of 2 elements list: 0
Please enter the values of 3 elements list: -7
Please enter the values of 4 elements list: 97
Please enter the values of 5 elements list: -88
Please enter the values of 6 elements list: 87
Please enter the values of 7 elements list: 77
Total positive number in the list= 4
Total negative number in the list= 2
Total zeros in the list= 1
