Python Press-Schechter function in python

[mahya]

I want to write program in python that gives "redshift", range of "M" and range of "dn/dM" as input and plots "Press-Schechter" function and delivers a graph as output. would you please give some hints? I'm beginner in programming and I don't know how to start.

A good place to start learning Python would probably be the tutorials over at python.org, for example:
https://docs.python.org/3.4/tutorial/introduction.html

The full tutorial can be found here:
https://docs.python.org/3.4/tutorial/index.html

If you can get some understanding of python, when it's time to do the calculation you'll probably need to make use of the Python math library:
https://docs.python.org/3.4/library/math.html

In particular you'll have to use math.exp(), math.pi, math.sqrt(), and math.pow().

To display the graph, try making use of pyplot:
