AAAD | Android library

I'm trying to write a program that tests every possible string before matching a specific string and also gives the number attempt. Take this example:

I'm trying to generate a list of all possible 4 characters permutation of the first 4 letters of the alphabet (i.e. aaaa, aaab, aaac, aaad, aaba...) I figured I'd go with nested for loop, but when I run the program, the for loops seem to be skipped altogether and I only see the "Number of chain printed 0"

What am doing wrong?

I'm trying to generate all the strings which contain only 4 lowercase English letters (from aaaa to zzzz) using OpenMP.

My idea is: create 4 nested loops, each loop generates 1 letter in the string.

Python 2.7

I have multiple files:

file A_01.txt filecontent: aaaa

file A_02.txt filecontent: bbbb

file B_01.txt filecontent: aaaB

file B_02.txt filecontent: bbbB

file D_01.txt filecontentcontent: aaaD

file D_02.txt filecontentcontent: bbbD

I need to create "merged" file based on file prefixes,

for files start with A_0 create merged file merged_A.txt and put there content of all files starts with A_0,

merged_B.txt for files starting with B_

same for all files

Hi I am having a csv file . I have a column named internal and the values under this column are either True or False. I would like to manipulate the csv file using bash script commands. In short I want to rename the column header from 'internal' to 'accounttype' and the column values 'True' should be mapped to 'INTERNAL' and 'False' should be mapped to 'EXTERNAL'.

so following is my csv file named accounts.csv

I am busy implementing a lab for pen testers to create MD5 hashes from 4 letter words. I need the words to have a combination of lower and uppercase letters as well as numeric and special characters, but I just do not seem to find out how to combine any given characters in all orders. So currently I have this:

I would like to return the first non null value of the utm_source column from each group after running a group by function.

This is the code I have written:

I am trying to find the first non null value from the utm_source column, for each anonymous_id and create a new column named first and label it with the value of the first non null value.

I asked a somewhat similar question previously and then figured out that I could get the first non null value using .first(). However I am having troubles assigning this value to a new column.

Here is my code:

I would like to model the probability of an event occurring given the existence of the previous event.

To give you more context, I plan to group my data by anonymous_id, sort the values of the grouped dataset by timestamp (ts) and calculate the probability of the sequence of sources (utm_source) the person goes through. The person is represented by a unique anonymous_id. So the desired end goal is the probability of someone who came from a Facebook source to then come through from a Google source etc

I have been told that a package such as sci.py gaussian_kde would be useful for this. However, from playing around with it, this requires numerical inputs.
