I notice a few comments scattered about various parts of this thread so I'll try and address as much as possible here.

There seems to be confusion regarding the idea of a program to support female python developers. Why female developers? Why not male ones too? This is what is causing the confusion that there's some sort of discrimination happening. However that's not really the case, and you have to look at the whole picture to really see it.

So, there's a problem of equality in the workplace as a general philosophy. Sexism, Ageism, Racism, you name it. Taking from a Japanese proverb "He who runs after two hares will catch neither". In this case there's more than two hares, there's quite a lot in fact. So we have to break the problem down into manageable components. In this case someone decided to take the women in tech approach to the problem and focus on it. I'd consider it like taking someone with knowledge of databases and let them work on the database specific problems.

Now then, what exactly is the issue with women in the IT field? Up until the hiring chain and through the workplace experience, there are points to where women don't get the chance they should get. One reason is that people may not see engineering as a "female appropriate job", as though women should be working as secretaries or fashion designers. Another problem is fear. There is fear that going into a job a woman might get harassed or otherwise have difficulty fitting into a primarily male dominated environment. Start-ups for example often have laid back environments where the line between professional an personal gets somewhat fuzzy. Someone slips and lets out an inappropriate comment because they're having a conversation with another coworker which resembles a talk at a party, and are unaware that they're still in a professional environment. This becomes difficult.

So you have women who are trying to get their foot in the door, but are not sure how. That's why we need groups like this. First off we need people to show support. We need people to say "hey women in IT is possible, here's some of us that are doing it". We also need men in on this too so they can be educated on what women in IT may have to deal with and know what to avoid. They're also needed to show that not all guys have this thing against women in IT and that things can work out for the better. Finally we also need it so that women can do networking with companies that are more aware of the issues that women deal with in the workplace, and actively work to figure out how to deal with it.

This is why these sort of organizations need to be in place, and why they need to target women specifically. They need to see others like them working towards the same goal so they can achieve their dreams knowing they have support.

Now with that in mind there is point to watch out for, and what I believe is a valid concern. That is that we don't want the women in IT movement to become a "women are better than men" deal, we want it to become a "women should have the same opportunities as men". Equality is our main goal here. However, because of the environment I've mentioned above, we need groups that specifically target women to help the transition towards a more equality friendly environment.

Hope this gives a better sense of what's happening.
