Python – How to replace whitespaces with underscore


I want to replace whitespace with underscore in a string to create nice URLs. So that for example:

"This should be connected" becomes "This_should_be_connected" 

I am using Python with Django. Can this be solved using regular expressions?

Best Solution

You don't need regular expressions. Python has a built-in string method that does what you need:

mystring.replace(" ", "_")
