Could someone explain why this error appears? the program asks for a word, and makes a pyramid with the word.

palavra = input('Digite a palavra:').upper()
lista = list(palavra)
x = 0 #ímpares
y = 0 #contador
z = len(palavra) #conta o numero de letras mais o add

while y < z:
    if (x%2) == 0:
        x  = 1
    else:
        p = lista[y]*x
        print(p.rjust(z))
        x  = 1
        y  = 1
        z  = 1

CodePudding user response：

I think z shouldn't be increased in the while loop other wise you will never end the while loop

palavra = input('Digite a palavra:').upper()
lista = list(palavra)
x = 0 #ímpares
y = 0 #contador
z = len(palavra) #conta o numero de letras mais o add

while y < z:
    if (x%2) == 0:
        x  = 1
    else:
        p = lista[y]*x
        print(p.rjust(z))
        x  = 1
        y  = 1
        # z  = 1

This will fix your error. Try this,

palavra = input('Digite a palavra:').upper()
lista = list(palavra)
print(lista)
x = 0 #ímpares
y = 0 #contador
z = len(palavra) #conta o numero de letras mais o add

while y < z:
    if (x%2) == 0:
        x  = 1
    else:
        if(len(palavra)-1 < y):  #Check the length of string and y value to end the loop
            break
    
        p = lista[y]*x
        print(p.rjust(z))
        x  = 1
        y  = 1
        z  = 1

Output like this,

CodePudding user response：

You are incrementing 'y' in iteration & that's make the issue. And the last iteration the it will always pointing to length of the string and list index on that time doesn't exist

 palavra = input('Digite a palavra:').upper()
 lista = list(palavra)
 x = 0 #ímpares
 y = 0 #contador
 z = len(palavra) #conta o numero de letras mais o add
 strlen = len(palavra) #conta o numero de letras mais o a

while y < strlen:
  if (x%2) == 0:
    x  = 1
  else:
    p = lista[y]*x
    print(p.rjust(z))
    x  = 1
    y  = 1
    z  = 1

Your code is ineffiecient and not working properly.

The first thing to do is to use functions, so that you can reuse your code.

The second thing you should do is to use str.center method.

The mathematical relationship between the indices and the strings is that each string has the length of its index times two (0 based indexing).

So I reimplemented your code:

from string import ascii_lowercase

def pyramidize(s):
    l = (len(s) - 1) * 2   1
    return '\n'.join([(c * (i * 2   1)).center(l) for i, c in enumerate(s)])
    
print(pyramidize(ascii_lowercase))

                         a                         
                        bbb                        
                       ccccc                       
                      ddddddd
