BMI calculator in Python
The main issue I see is inconsistent style. Sometimes you put spaces around certain operators, sometimes you don't. You want your code to be consistently formatted.

Generally, it's best to always put a space before and after an operator, especially the assignment operator. It's even more strange to put a space before an operator, but not after (or vice versa).

This line, for example:

age= float(raw_input("How old are you %s?   &gt;   " %name))


would look much better like this:

age = float(raw_input("How old are you %s?   &gt;   " % name))


You also switch between putting a space after commas in lists, and not doing so. I would change these lines:

male=["male","m"]

female=["female", "f"]


to look like this (notice the space after the first comma):

male = ["male", "m"]

female = ["female", "f"]


Variables should always begin with a lowercase letter. Classes and constants can and should be capitalized, but not normal variables. So the Gender variable should be renamed to gender.

You should consider not asking for the user's gender and age unless you actually do something with that data, or at least don't assign it to variables because it'll go unused.

I would also rename bmi_q, bmi_c, and consent_q to something more clear, so other people reading your code can immediately know what those function are supposed to do. bmi_c could definitely be renamed to something like calculate_bmi, or even calc_bmi.

And lastly, I'd always make sure your indention doesn't get messed up when pasting your code into a site like this. There's a few problems with invalid indention, but I'd imaging that happened when you put it in this question. (the indention in the question has been fixed now though)

But overall, good job on writing your first program! Congrats, keep it up, and remember this quote from Phil Karlton:
