Hello,
I have column "Gender" column  with values "Male" and "female" 
I want to replace Male with "M"  and female with "F"

how can i do this

Many options. The easiest is to use the replace operator twice, first to replace female with F and then Male with M.

Another would be to use the generate attribute operator, and use some combined functions.

You generate the attribute Gender (you actually recreate it) and use prefix(upper([Gender]), 1) for instance.
