Answer :-

(i).

for i in range(6):
      for j in range(6):
            if i >= j :
                  print(chr(65+j)+" ",end="")
      print()

(ii).

for i in range(4):
    if i == 0 :
            print(0)
            continue
    for j in range(i+1):
        print(str(2**i),end="")
    print()

Alternate program :-

for i in range(4):
      if i == 0 :
            print(0)
      else:
            print(str(2**i)*(i+1) )
