Hi all, this is a newbie question on : Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32 PC with WinXP
In http://www.python.org/doc/2.3.5/lib/module-math.html I read: "sqrt( x) Return the square root of x." Now the test for module math with function pow(): --------------------------------------------------- >>> pow(9,9) 387420489 Fine, but sqrt() fails: ------------------- >>> sqrt(9) I get this error message 'Traceback (most recent call last): File "<pyshell#3>", line 1, in <module> sqrt(9) NameError: name 'sqrt' is not defined' Same for sin() and cos(). ">>> Import math" does not help. Will I have to define the sqrt() function first? If so, how? Please help! Thank you, Siggi -- http://mail.python.org/mailman/listinfo/python-list
