title: Change a variable name in all places in Python
body: <p>I have written a code in Python3 using the IDE Wing, but I want to change a variable name, e.g., <code>var_1</code>, to <code>var_2</code> in all places in my file. In MATLAB, when you change a variable name in one place, by <code>Shift</code>+<code>Enter</code> it is automatically done for all other occurrences of that variable in the file. Is there any similar way to do it in Python?</p>
