Python: Concatenation
In web development, programs use strings all the time. Everything we see on websites, in one way or another, is presented as text. This text is most often dynamic, i.e., it comes from different parts that are joined together.
To combine strings, you have to perform concatenation:
# The operator is the same as for adding numbers,
# but here it has a different meaning (semantics)
print('Dragon' + 'stone') # => DragonstoneStrings are always concatenated in the order in which the operands are written. The left operand becomes the left part of the string, and the right one becomes the right part. Here are a few more examples:
print('Kings' + 'wood') # => Kingswood
print('Kings' + 'road') # => Kingsroad
print("King's" + 'Landing') # => King'sLandingAs you can see, strings can be concatenated even if they're written with different quotes.
Spaces are a character like any other, so how many spaces you put in a string is how many you get in the final string:
# Put a space in the left part
print("King's " + 'Landing') # => King's Landing
# Put a space in the right part
print("King's" + ' Landing') # => King's LandingInstructions

Winter came for the House of Frey.using concatenation.
If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:
- Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.

Your exercise will be checked with these tests:
import importlib
def test(capsys):
expected = "https://github.com/hexlet/exercises-python"
expect_output(capsys, expected)
def expect_output(capsys, expected):
importlib.import_module('solution')
out, _err = capsys.readouterr()
actual = out.strip('\n')
with capsys.disabled():
print('\n')
print(out)
assert actual == expectedTeacher's solution will be available in:
