What is the regex expression to extract 3 letter word starting with M followed by 2 number? : <p>I want to extract first 3 letters of the sentence which start with M and are followed by 2 digits. </p>

<p>If sentence is M30 INTHE SKY then output should be M30. IF sentence is THE INTHE SKY then answer should be np.nan(i.e. false as it didnot start with M)</p>
