Python has a built in string type, supporting many useful methods.
given = "John"
family = "Doe"
full = given + " " + family
John Doe
So + for strings means “join them together” - concatenate.
Other useful methods include:
print(full.upper())
JOHN DOE
As for float and int, the name of a type can be used as a function to convert between types:
ten, one
(10,1)
print(ten + one)
11
For example, can then convert to a string, before converting back to float:
print(float(str(ten) + str(one)))
101.0
We can remove extraneous material from the start and end of a string:
" Hello ".strip()
‘Hello’
Note that you can write strings in Python using either single (‘ … ‘) or double (“ … “) quote marks. The two ways are equivalent. However, if your string includes a single quote (e.g. an apostrophe), you should use double quotes to surround it:
"John's Class"
“John’s Class”
And vice versa: if your string has a double quote inside it, you should wrap the whole string in single quotes.
'"Wow!", said Bob.'
‘“Wow!”, said Bob.’
