What is the difference between str and repr in Python?
In Python, str
is used to represent a string in a more readable format, while repr
is used to represent a string in an unambiguous and official format. The main difference between the two is that str
is meant to be more user-friendly, while repr
is meant to be more machine-friendly.
For example, consider the following code:
s = 'Hello, world!'
print(str(s))
print(repr(s))
This will output the following:
Hello, world!
'Hello, world!'
As you can see, the output of str(s)
is more readable, while the output of repr(s)
includes quotes around the string to make it clear that it is a string.
In general, you should use str
when you want to display a string to the user, and repr
when you want to represent a string in a way that can be used to recreate the original object, such as in a debugger or when logging the state of an object.
