I am trying to open a CSV file but for some reason python cannot locate it. Here is my code (it’s just a simple code but I cannot solve the problem):
You can’t solve it. Simply answer1.sum()==0, and you can’t perform a division by zero. This happens because answer1 is the exponential of 2 very large, negative numbers, so that the result is rounded to zero. nan is returned in this case because of the division by zero. Now to solve your problem you could: go … Read more
I don’t know why no one has mentioned this yet, because it’s fundamental to the way with works. As with many language features in Python, with behind the scenes calls special methods, which are already defined for built-in Python objects and can be overridden by user-defined classes.

Recently I have started programming in Python (Python 3.5) on my Linux OS. But I am confused about Anaconda. What is it actually? Is it a version of Python or something else? If I do not install Anaconda will there be any limitations?
e.g, keep.update(xrange(11)) for your specific example. Or, if you have to produce the values in a loop for some other reason, But, of course, doing it in bulk with a single .update call is faster and handier, when otherwise feasible.
Python 3 In Python 3, this question doesn’t apply. The plain int type is unbounded. However, you might actually be looking for information about the current interpreter’s word size, which will be the same as the machine’s word size in most cases. That information is still available in Python 3 as sys.maxsize, which is the … Read more
If you’re using zsh and it has not been set up to read .bashrc, you need to add the Miniconda directory to the zsh shell PATH environment variable.
