A B C
rows=int(input("Enter number of rows : "))
for i in range(1,rows+1):
  c=65
  for j in range(1,i+1):
    print(chr(c),end=" ")
    c+=1

Program
pattern

Main logic :

for i in range(1,rows+1): #rows : number of rows to print
  c=65  #"A" starts from 65
  for j in range(1,i+1):
    print(chr(c),end=" ")
    c+=1
  print("")

You can print the same pattern in small alphabets, just set c=97
