Beginner Python student here. Here's my attempt at it, a very literal approach, using two For loops:

pascal = [[1]]
num = int(input("Number of iterations: "))
print(pascal[0]) # the very first row
for i in range(1,num+1):
    pascal.append([1]) # start off with 1
    for j in range(len(pascal[i-1])-1):
    # the number of times we need to run this loop is (# of elements in the row above)-1
        pascal[i].append(pascal[i-1][j]+pascal[i-1][j+1])
        # add two adjacent numbers of the row above together
    pascal[i].append(1) # and cap it with 1
    print(pascal[i])
