While calling, I am looking not only to print, but to use them or manipulate them. I hope I am bit clear now. Best Regards, Subhabrata.

Your function1 and function2 should return the values they compute instead of printing them out. -- regards, kushal

For example: >>> def add(x, y): .... return x + y .... >>> def mul(x, y): .... return x * y .... >>> def sum_of_squares(x, y): .... return add(mul(x, x), mul(y, y)) .... >>> sum_of_squares(3, 4) 25 OP: If that addresses your question I suggest that you work through some introductory text about python. The python wiki has a few suggestions, see http://wiki.python.org/moin/BeginnersGuide Peter

Though I did not get the exact answer but from Peter's link I could work them out. Thank you, Peter, for kindly referring me the link. I like to thank others of the group also for kindly spending their valuable time. I wanted to define one function and call the value of that function to be used by another function. If I misquoted the problem, I am sorry. Wishing You all a Great Day Ahead, Best Regards, Subhabrata. |
