How to declare an array in Python?
How do I declare an array in Python? I can’t find any reference to arrays in the documentation.
Searching the student-t distribution table for values using python
For a meaningful interpolation, you would first need to define a 2D inperpolation function (bilinear, bicubic). For better resutls directly use the scipy implementations of the percent point function (i.e. the inverse cumulative distribution function). Result is v: 2.57058 so the result is the same as the 2.571 from your table. This code reproduces your … Read more
What does enumerate() mean?
The enumerate() function adds a counter to an iterable. So for each element in cursor, a tuple is produced with (counter, element); the for loop binds that to row_number and row, respectively. Demo: By default, enumerate() starts counting at 0 but if you give it a second integer argument, it’ll start from that number instead: … Read more

How can I reverse a list in Python?
You can make use of the reversed function for this as: Note that reversed(…) does not return a list. You can get a reversed list using list(reversed(array)).
Difference between del, remove, and pop on lists
The effects of the three different methods to remove an element from a list: remove removes the first matching value, not a specific index: del removes the item at a specific index: and pop removes the item at a specific index and returns it. Their error modes are different too:
can’t multiply sequence by non-int of type ‘float’
should be: You are multiplying 0.01 with the growthRates list object. Multiplying a list by an integer is valid (it’s overloaded syntactic sugar that allows you to create an extended a list with copies of its element references). Example:
