def print_pattern(n):
    # we need to run two for loops. Outer loop prints patterns line by line
    # where as inner loop print the content of that specific lines
    for i in range(n):
        s = ''
        for j in range (i+1):
            s = s + '*'
        print(s)
print_pattern(5) 

Adding the list values using for loops:

exp= [123,456,789,120]
total=0
for item in exp:
    total=total + item
print(total)
