How is the result of displaying a variable through the print() function different from accessing it directly?

Question

Python

Actually the whole question is described in the title
I do not understand the difference.
I see that in dictionaries with a long value, the output result is slightly different

Answer 1

Some development environments allow you to display the contents of a variable. For example, Jupyter or an interactive python interpreter. But this is not a python feature, it is a development environment feature. Simplifying, for each expression, the environment executes something like this:

result = введённое_тобой_выражение
if result is not None:
    print(repr(result))

And here are ways to convert an object to a string in python and indeed 2.
str(some_object) should give a human-readable representation.
repr(some_object) should (if possible) give a representation that describes that object in python syntax.
A good example is strings.
print(str("foo\nbar")) will print

foo
bar

Whereas print(repr("foo\nbar")) will print

"foo\nbar"

But for many objects there is neither a smart str() nor a smart repr(), so the two representations are the same.

Answer 2

Apparently this is Jupiter and Ipynb's notebook.
And you try to output through the command line without a print) Or in the standard python IDE. We will see)
