External data quality can affect downstream systems, reporting, and metrics and cause vulnerabilities in our systems. Using the templated code provided, write one method to check if a string is not null and a separate method to check if a string contains all numbers.

Your first variable will be a string and contain a simple sentence, such as "I like dogs." Your second variable will be an integer and will contain a few numbers, such as 12345.

Complete the functions in the code template.

For example, if the variables in the templated code are:

I like dogs.
12345

The output to the console will be the following:

True
True

Alternatively, if the variable values in the template code are changed to:

None
12345

The output to the console will be the following:

False
True

Alternatively, if the variable values in the template code are changed to:

None
"I love dogs"

The output to the console will be the following:

False
False

# verify we only have digits

def check_numeric_value(wg_int):
    
        #return true if numeric value is an integer, else return false.  
        #Hint: use isinstance function

# verify if the string is null

def check_null_string (wg_string):
    
    # check if wg_string is not null return true else return false
       
if __name__ == '__main__':  
    
    wg_string = "I like dogs." # use keyword None to test
    wg_int = 12345
    
    print(check_null_string (wg_string))
    print(check_numeric_value(wg_int))
