Python error

[iHammmy]

Hello,

 

Whenever I try to enter a ( " ) in Python, it double prints the ( " ) key, so I end up with two. Does anyone know how to fix this?

 

Example:

print ("But it ends up doing...print (""

Thanks in advance,

 

- Harry

Are you using PyScripter? If so it does that auto matically

[Enderman]

try doing

print(/")

the backslash makes it take the " as a character and cancels its "string" functionality

try doing

print(/")

That's a forward slash

Most IDE's are going to do that automatically for you. They assume that certain things, such as brackets have to be closed at some point again anyway, same with Literals / Strings like in your case. You will have to close it at the end again anyway, making it look like this:

 

print ("Hello")

 

So, the IDE fills in the closing bracket and second " for you.

Nope, IDLE.

I don't quite understand the string functionality. Any chance you could explain it to me?

oops sorry i mean to type a backslash

in python doing this "potato" makes potato a string (sentence of text)

the double quotes define what is between them as a string

you cant print it by just doing " because its not a piece of text

 

by putting a backslash before the " you cancel its function turning it into a text character that you can print

[madknight3]

Nope, IDLE.

A string is enclosed in single or double quotes in python. If you want to have the quotes inside the string you can do the following.

# wrap in double quotes, can use single quotes inside the stringprint ("hello'world") # prints hello'world# escape the double quotes so it can be used inside a string with double quotesprint ("hello\"world) # prints hello"world# escape the single quotes so it can be used inside a string with single quotesprint ('hello\'world) # prints hello'world# wrap in single quotes, can use double quotes inside the string without escapingprint ('hello"world) # prints hello"world

Other characters need to be escaped (backslash in front of them) as well.

Nope, sorry Thanks anyway

[Enderman]

Nope, sorry Thanks anyway

try

print("\"")

i might have forgotten the outer doublequotes

[iHammmy]

 

try

print("\"")

I don't mean there is a problem with the strings, I mean that whenever I enter the " key it prints it twice...

Sounds like it's your editor automatically closing the string for you. I don't consider that to be a problem personally. If you don't want that, then you may be able to change your editors settings to stop it.

oooh sorry i misunderstood the issue here...

 

make sure you are using the ' key no the " key,

make sure your editor is not auto-closing strings

and try copy pasting ' instead of typing, see if that changes anything

Just use ' instead of ". You don't have to shift and it functions in the same way. Make it a habit, it'll be a good one.

It still prints two '

Get a new text editor. Try out Notepad++
