Hi Manisha,

Can you please let me know the errors you are getting when you try to execute the same commands ?
Also, please make sure are specifying the proper paths when you try to save the plot or when you are trying to open the file.

The paths we have used in the tutorial for saving the plot & to open the primes.txt file are just for illustration (you have to give relative paths to your directory).

1) i have put my ipython folder in' H ' drive and installed anacond ,and during the drawaing plot like "plot(x,cos(x))" only blank white screen page of figure is coming ,as well as during saving , i applied like savefig('h/file_name.png') .but it gives error like "no such file or directory: ' h/sin.png' " is coming .

2) in video 2-1 when i used /cat/home/fossee/primes.txt or /cat/h/primes.txt ,it gives error like invalid syntax.

so please tell me what is problem.

1. before plotting you have to define the points first as shown in the tutorial. So, the steps would be:
--> start ipython by typing ipython -pylab
--> x = linspace(-3*pi, 3*pi, 100)
--> plot(x, cos(x))
--> savefig('h:\cos.png')
this should definitely work.

2. To open a file you have to type:
--> cat <full path of the directory where the file is>
so if it is in your h drive then
--> cat h:\primes.txt

Thanks
