Is there a keyboard shortcut in Pycharm for renaming a specific variable?

问题

I'm using Pycharm for Python coding, and I want to change the name of a specific variable all over the code. is there any keyboard shortcut for this operation?

In Matlab I can use ctrl + shift.

For example:

old_name=5
x=old_name*123

will become:

new_name=5
x=new_name*123

without the need to change both of the old_name references.

Thanks!

Highlight your old_name and hit Shift+F6

I don't know about a shortcut for this special purpose, but I simply use Ctrl+R to replace the old variable names with new ones. You can also set settings such as Match case, Regex or In selection.

Note that this won't work, if you have a variable name including another variable name:

var1 = 0
var1_s = "0"

Replacing var1 to xy would result in :

xy = 0
xy_s = "0"

But that also forces you to do consistent and clear variable naming.
