# verify we only have digits
def check_numeric_value(wg_int):
return isinstance(wg_int, 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)) correct answer return
isinstance(wg_int, int)


return wg_string is not None


#check if the input range is between 1 and 10 for the range validation
check
if __name__ == '__main__':


r = range(1,10)


num = int(input())


# create conditional statement for range check here correct answer r =
range(1,11)


num = int(input())


if num in r:
print("The number input is in the range from 1 and 10.")
else:
print("The number input is not in the range from 1 and 10.")
