Understanding repr( ) function in Python

Question

repr(): evaluatable string representation of an object (can "eval()" it, meaning it is a string representation that evaluates to a Python object)

In other words:

>>> x = 'foo'

>>> repr(x)

"'foo'"

Questions:

1. Why do I get the double quotes when I do repr(x)? (I don't get them when I do str(x))

2. Why do I get 'foo' when I do eval("'foo'") and not x which is the object?

Answer 1

You can understand by seeing the below-mentioned code:-

foo = 'bar' 

baz(foo)

you are not passing foo to the baz function. foo is just a name used to represent a value, in this case, 'bar', and that value is passed to the baz function.
