Answer:
Following are the program in the Python Programming Language:
def check(num): #define function
if(num.isdigit()): #set if statement
return "yes"; #return yes if condition is true
else:
return "no";# return no if condition is false
string=input("Enter the numbers 0-9: ") #get input from the user
print(check(string)) #print and call the function
Output:
Enter the numbers 0-9: 1995
yes
Enter the numbers 0-9: 42,000
no
Explanation:
Here, we define a function "check()" and pass an argument in its parameter "num" inside the function.
- we set if-else conditional statement and check the value stored in the variable "num" is the digit by using built in function "isdigit()" then return "yes".
- Then, otherwise it return "no".
Finally, we get the input from the user in the variable "string" then, we call the function through "print()" function.
