Python : How to check if a variable is equal to '' ''

Question

I have a variable:

exchange_name = ''

Now I want to perform some operation based on checking if it is equal to an empty string.

So, I do:

if exchange_name == '':
  # perform some operation

But how can I generalize the solution so that exchange_name can contain any number of spaces, e.g.:

exchange_name = ' '

or

exchange_name = '  '

Can anybody suggest an approach? Thanks in advance.

You just need to trim white space from your variable and compare that result to the empty string. The strip function will do this for you. — Brian Driscoll, Apr 26 '18 at 01:11

exchange_name.strip()==''

strip removes all empty spaces.

Try to use rstrip to remove spaces from begin and end of string.

if mytext.rstrip() == '':
    do_it()
