Replace Single Quotes with Double Quotes in a Python String

In this tutorial, we will look at how to replace single quotes in a Python string with double quotes with the help of some examples.

Replace ' with " inside a string

Let’s see an example to better understand the task at hand. Let’s say you have the string, "This is a 'safe' place". After replacing the single quotes with double quotes, the resulting string should be 'This is a "safe" place'.

How to replace single quotes with double quotes in a string?

You can use the following methods to replace single quotes with double quotes in a Python string.

1. Using the string replace() function to replace all single quotes with double quotes.
2. Using a translation table to map every single quote with a double quote.

Let’s now look at both these methods with the help of some examples.

Example 1 – Using the string replace() function

The built-in string replace() function used to replace occurrences of a string with another string. To replace single quotes with double quotes, pass a single quote as the first argument and a double quote (using escape sequence) as the second argument.

Let’s look at an example.

# create a string
s = "This is a 'safe' place"
# display the string
print(s)
# replace single quotes with double quotes
res = s.replace("'", """)
# display the result
print(res)

Output:

This is a 'safe' place
This is a "safe" place

You can see that the single quotes have been replaced by double quotes in the resulting string.

Example 2 – Using the string translate() function

The string translate() function is used to apply a translation map on a string. Use the str.maketrans() function to create a translation map (also called translation table), mapping quotes to double quotes.

Let’s look at an example.

# create a string
s = "This is a 'safe' place"
# display the string
print(s)
# replace single quotes with double quotes
res = s.translate(str.maketrans({"'": """}))
# display the result
print(res)

Output:

This is a 'safe' place
This is a "safe" place

The single quotes have been replaced by the double quotes in the resulting string.
