Convert single-quoted string to double-quoted string

Question

I want to check whether the given string is single- or double-quoted. If it is single quote I want to convert it to be double quote, else it has to be same double quote.

Answer 1

There is no difference between "single quoted" and "double quoted" strings in Python: both are parsed internally to string objects.

I mean:

a = "European Swallow" b = 'African Swallow' 

Are internally string objects.

However you might mean to add an extra quote inside an string object, so that the content itself show up quoted when printed/exported?

c = "'Unladen Swallow'" 

If you have a mix of quotes inside a string like:

a = """ Merry "Christmas"! Happy 'new year'! """ 

Then you can use the "replace" method to convert then all into one type:

a = a.replace('"', "'")  

If you happen to have nested strings, then replace first the existing quotes to escaped quotes, and later the otuer quotes:

a = """This is an example: "containing 'nested' strings" """ a = a.replace("'", "\\\'") a = a.replace('"', "'") 

Answer 2

Sounds like you are working with JSON. I would just make sure it is always a double quoted like this:

doubleQString = "{0}".format('my normal string') with open('sampledict.json','w') as f:     json.dump(doubleQString ,f) 

Notice I'm using dump, not dumps.

Sampledict.json will look like this:

"my normal string"
