Question
In Python, how do you return a variable like:
function(x):
return x
Without the 'x'
('
) being around the x
?
Solution
In the Python interactive prompt, if you return a string, it will be displayed with quotes around it, mainly so that you know it's a string.
If you just print the string, it will not be shown with quotes (unless the string has quotes in it).
>>> 1 # just a number, so no quotes
1
>>> "hi" # just a string, displayed with quotes
'hi'
>>> print("hi") # being *printed* to the screen, so do not show quotes
hi
>>> "'hello'" # string with embedded single quotes
"'hello'"
>>> print("'hello'") # *printing* a string with embedded single quotes
'hello'
If you actually do need to remove leading/trailing quotation marks, use the .strip
method of the string to remove single and/or double quotes:
>>> print("""'"hello"'""")
'"hello"'
>>> print("""'"hello"'""".strip('"\''))
hello
OTHER TIPS
Here's one way that will remove all the single quotes in a string.
def remove(x):
return x.replace("'", "")
Here's another alternative that will remove the first and last character.
def remove2(x):
return x[1:-1]
