I am doing a program to sort the entered numbers (I can not simply use a sort algorithm), searching vi that can not change strings in python, have any way to do this? Or maybe use list instead of string?
entrada = "32415"
for i in range(entrada):
if entrada[i] > entrada[i+1]:
aux = entrada[i]
entrada[i] = entrada[i+1]
entrada[i+1] = aux
print(entrada)
First of all, remembering that python has much more efficient sorting algorithms already implemented in the language, just call a function to sort:
entrada = ''.join(sorted(entrada))
But, answering your question: yes, lists are mutable, you can convert your string to list:
entrada = "32415"
entrada = list(entrada)
Your sorting algorithm has some problems, it looks like you're trying to use the "bubble method", however you need to get back to wherever there is a trade, in which case it would be best to use while instead of for :
i = 1
while i < len(entrada):
if entrada[i] < entrada[i-1]:
entrada[i], entrada[i-1] = entrada[i-1], entrada[i]
i = max(1, i - 1)
else:
i += 1
Then in the end you can convert the result back to string using join :
entrada = ''.join(entrada)
print(entrada)
The result:
12345
Hello, how are you? : D
I do not know if you are studying algorithms for sorting or want a practical solution of Python, but I will follow the second option.
To sort your entry variable, one possibility could be as follows:
entrada = '32415'
# Nos dois próximos comandos a string vai virar uma lista.
# Em ordem crescente.
entrada = sorted(entrada)
# Ordem decrescente.
entrada = sorted(entrada, reverse=True)
# Converter de volta para string.
entrada = ''.join(str(a) for a in entrada)
I do not know if this is what you want, but I hope so: D
