Python code to check whether the given number is positive or negative or 0

In this tutorial, we will discuss the Python code to check whether the given number is positive or negative or 0

In this post, we are going to learn how to check whether the given number is positive or Negative or zero using 3 ways in Python language

The logic to check positive, negative or zero

Check the condition if(num<0), then number is negative
Check the condition if(num>0), then number is positive
Check the condition if(num==0), then number is zero

Python code to check whether the given number is positive or negative or 0

Check whether the given number is positive or negative or 0- using standard method

Program 1

#Pyton program to check number is positive or negative or zero
num=234
if(num>0):
    print("{0} is a positive number".format(num))
elif(num<0):
    print("{0} is a negative number".format(num))
else:
     print("you have entered zero")

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

234 is a positive number

In this program,

integer variables num is declared and initialized
The given numbers are tested whether it is positive, negative or zero using if- elif statements
Then,the program is displayed the output of using print() function

Check whether the given number is positive or negative or 0- using User input

Program 2

#Pyton program to check number is positive or negative or zero
num=int(input("Enter the number: "))
if(num>0):
    print("{0} is a positive number".format(num))
elif(num<0):
    print("{0} is a negative number".format(num))
else:
     print("you have entered zero")

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

Case 1

Enter the number: 124
124 is a positive number

Case 2

Enter the number: -765
-765 is a negative number

Case 3

Enter the number: 0
you have entered zero

Approach

integer variable num is declared.
The program asks input from the user
Then the user enters the input values for num.
The program will read the input using input stream and store to the variable num
The given number is tested whether it is positive, negative or zero using if- else statements
Then,the program is displayed the output of using print() function,

Check whether the given number is positive or negative or 0- using function

Program 3

#Pyton program to check number is positive or negative or zero
num=int(input("Enter the number: "))
def FindPositive():
  if(num>0):
    print("{0} is a positive number".format(num))
  elif(num<0):
    print("{0} is a negative number".format(num))
  else:
     print("you have entered zero")
#FindPositive();

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

Case 1

Enter the number: 36
36 is a positive number

case 2

Enter the number: -75
-75 is a negative number

case 3

Enter the number: 0
you have entered zero

Approach

integer variables num is declared.
The program asks input from the user
Then the user enters the input values for num.
The program will read the input using input stream and store the variable num.
Define the function findPositive(); to find whether the number is Negative or Positive or zero
Call the function to produce output
finally, the program displays the output using print().
