I am trying to make a program that makes the letters of the alphabet in triangle type so the user enters with an integer number and the result is displayed in triangle form.

7:
A

BB

CCC

DDDD

EEEEE

FFFFFF

GGGGGGG

4:
A

BB

CCC

DDDD

I’ve tried wearing the bow tie for but I couldn’t. Follow my attempt:

N = int(input())

if N == 1:
    print('A')
if N == 2:
    print('A\n'
          'BB')
if N == 3:
    print('A\n'
          'BB\n'
          'CCC')
if N == 4:
    print('A\n'
          'BB\n'
          'CCC\n'
          'DDDD')
if N == 5:

if N == 6:
    print('A\n'
          'BB\n'
          'CCC\n'
          'DDDD\n'
          'EEEEE\n'

    Could you show us how you did with the bow tie for?

The module string from the standard python library defines some constants among which string.ascii_uppercase is the sequence of capital letters ABCDEFGHIJKLMNOPQRSTUVWXYZ.

It is possible enumerate and iterate for a slice, the size chosen by the user, the sequence of letters and each iterated element the print repeatedly with the help of the operator * sequential repeat:

import string

N = int(input("Digite a altura da pirâmide:"))
#Itera pela fatia de caracteres onde i é índice e c é o caractere com o índice começando em 1... 
for i,c in enumerate(string.ascii_uppercase[:N], 1):
  print(c*i);         #...imprime o caractere o repetindo i vezes.

For this you can use the global functions of Python as a chr.

# Quantidade de linhas
value = int(input("Digite: "))

# Executa a quantidade de vezes digitada
# inicialmente, para cada nova iteração
# ele printa uma nova letra
for i in range(value):
    for j in range(i + 1):
        # Mostra o caracter n vezes
        print(chr(65 + i), end="") # 65 = 'A' na tabela ASCII
    print("")
