Strings Flashcards
Strings are used when you need to process text (like names of all kinds, addresses, novels, etc.),
not numbers.
Let’s assume that we want to print a very simple message saying:
I like “Monty Python”
How do we do it without generating an error? There are two possible solutions.
escape character, which you should remember is played by the backslash. The backslash can escape quotes too. A quote preceded by a backslash changes its meaning - it’s not a delimiter, but just a quote. This will work as intended:
print(“I like "Monty Python"”)
second solution may be a bit surprising. Python can use an apostrophe instead of a quote. Either of these characters may delimit strings, but you must be consistent.
If you open a string with a quote, you have to close it with a quote.
If you start a string with an apostrophe, you have to end it with an apostrophe.
This example will work too:
print(‘I like “Monty Python”’)
Note: you don’t need to do any escaping here.
We’ve shown it already, but we want to emphasize this phenomenon once more - a string can be empty - it may contain no characters at all.
An empty string still remains a string:
’’
“”
