appending list of list - glennford49 - Mar-29-2020
whats wrong with my code?
i cant get the desired output
list1=[]
list2=[]
num=[1,2,3,4,5,6]
while(True):
if (len(list2)<=2): # generating numbers
n = random.choice(num)
list1.append(n)
list1.sort()
num.remove(n)
if(len(list1)==3): # appending to list if it has 3 elements
list2.append(list1)
num=[1,2,3,4,5,6] #declaring num list again
else:
print("no")
break
print("list2",list2)# printing 3 elements in format [[x,x,x],[x,x,x],[x,x,x]] <=== desired output

When you get output you do not understand you had best add print statements to your code to see step by step what is really happening. You may add print statements to show the value of num, list1 and list2 just before or after you change them.
(Hint: concentrate on list1.)
