I’m trying to delete control sequences (\n, \t, \u) of strings in Python and I can’t even with replace, nor with re.sub(). How could I do?

I tried, and they didn’t work :

p = re.sub('\n', '', p)


p.replace("\n","")
python string replace

    Can you put the whole code? With replace should work, so the error must be somewhere else in the code. You are capturing the return of the method, p = p.replace('\n', '')? If not, possibly that’s the mistake.

With the replace is possible, just re-assign the output to the variable. 

minha_string = "teste \n teste"
print(minha_string)
print("==============================")

minha_string = minha_string.replace('\n', '')
print(minha_string)

Exit: 

teste
 teste
==============================
teste  teste

Simple, just use the function that removes control characters that are rstrip() right. Then in practice it would be:

SuaString = SuaString.rstrip()

Ready, now your string will no longer have the control characters! ;-)
