How can I efficiently find distances from each value to the next lower/higher value?
I’ll tell you what structures I am using, please feel free to recommend any changes like numpy arrays or something. Anyways what I have is a list of 5 million sequential entries that correspond to a stock price. I then have 2 more lists, each of these is the same length – 5 million entries. These lists correspond to an
Comparing two sequence columns, and base on a condition add element to Dataframe
Hello, I’m looking for a script in Python that can help me with the following problem: Having the following two columns, I need to create gaps between the sequences in order to make them match: Input Output Index column A column B column A column B 0 1 1 1 1 1 2 2 2 2 2 2 2 2
Sympy – Arithmetic and geometric sequence in recursive form
I would like to define arithmetic and geometric sequences in recursive form like Un+1 = Un + r (u0 n>0) Un+1 = qUn (u0 n>0) In Sympy, one can define in closed form an arithmetic sequence like this : How can I define (not solve) this sequence in recursive form (Un+1 = Un + r) ? Answer You’ll need to
With a string of numbers generate variations with addition, subtraction or nothing to make 100
I have a string of numbers, string=”123456789″ and I would like to print all variations, inserting addition, subtraction or nothing between the numbers to make 100.The order of numbers most remain unchanged. Example: 1+2+3-4+5+6+78+9=100 I am not sure how to even start. I thought of making a list of all possible combinations of +-x (x stands for nothing) and inserting
Sum of lowest numbers that are part of an arithmetic sequence
I would like to iterate through a list of integers, calculate the sum of the lowest numbers that belongs to an arithmetic sequence with common difference 1 + the numbers that are not part of a sequence: So, from mylist it would be 2 (from 2,3,4) + 10 (not part of a sequence) + 12 (from 12,13) I’ve managed to
Merging csv files in order of date created Python Pandas

Iterate over list selecting multiple elements at a time in Python
I have a list, from which I would like to iterate over slices of a certain length, overlapping each other by the largest amount possible, for example: In other words, is there a shorthand for zip(seq, seq[1:], seq[2:]) where you can specify the length of each sub-sequence? Answer [seq[i:i+3] for i in range(len(seq)-2)] is the Python code for something similar.
