Downloaded Python 3.9.0
Documentation indicates:
math.sqrt(x)
Return the square root of x.
When I use in IDLE shell 3.9.0, I receive error:
>>> sqrt(25)
Traceback (most recent call last):
File "<pyshell#11>", line 1, in <module>
sqrt(25)
NameError: name 'sqrt' is not defined
What is the problem?

You have to import the math module first and then reference the sqrt function of the math module. >>> import math >>> math.sqrt(25) 5.0 |

Mike, please ask questions on question forums such as python-list (mail.python.org) or stackoverflow.com, where other beginners can see the answer. Also, IDLE is not Python. In particular, python's response to code you send to python usually has nothing to do with IDLE. |
