Write a function called check_nums that takes a list as its parameter, and contains a while loop that only stops once the element of the list is the number 7. what is returned is a list of all of the numbers up until it reaches 7.

Following are the program in the Python Programming Language:

def check_nums(length): #define function

 my_lst=[]  #set list type variable

 n=0  #set integer type variable

 while(length[n] != 7): #set the while loop  

   my_lst.append(length[n])  #append liat in my_lst

   n+=1  #increament in n

   if(len(length)==n): #set if condition

     break  #break the loop

 return my_lst  #return the list

l=[4,6,2,55,16,7,81]  #set list variable and assign list init

print(check_nums(l)) #call and print the function

Output:

[4, 6, 2, 55, 16]

Explanation:

Here, we define a function "check_nums()" and pass an argument in its parentheses inside the function,

Finally, set the list type variable "l" and assign the list of numeric value in it then, call and print the function "check_nums"
