How do I replace whitespaces with underscore?

Question

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_conn         


        

Answer 1

OP is using python, but in javascript (something to be careful of since the syntaxes are similar.

// only replaces the first instance of ' ' with '_'
"one two three".replace(' ', '_'); 
=> "one_two three"

// replaces all instances of ' ' with '_'
"one two three".replace(/\s/g, '_');
=> "one_two_three"
