3. Using Pool() do the following: 3.1. The pool must have 2 processes, each process will pass two parameters to a search function, these parameters must be the name of the file and a word to search for, these two parameters must be entered by the user and must be different from the process to another. 3.2. The Search function must search for the word in the file and if the word is found then find out the number of occurrences for this word otherwise return that the word doesn't appear in the file. 3.3. You need to verify that the file the user inserted is actually a file and it exists in the system.

Examine the following three functions that take as argument a file name and return the extension of that file. For instance, if the file name is 'myfile.tar.gz' the returned value of the function should be 'gz'. If the file name has no extention, i.e. when the file name is just 'myfile', the function should return an empty string. def get_extension1(filename): return(filename.split(".")[-1]) def get_extension2(filename): import os.path return(os.path.splitext(filename)[1]) def get_extension3(filename): return filename[filename.rfind('.'):][1:] Which of the these functions are doing exactly what they are supposed to do according to the description above? get_extension3 only get_extension2 only None of them. get_extension1 only
Do not copy paste from any source else downvote Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.
Learn the difference between a file extension and the function it serves in the job that you do by familiarizing yourself with both.
1. Assume that there is a valid file cards.txt in the current directory which contains 5 valid int values, each on its own line. Write a function which reads all the values from the file and prints out the message “Lucky 7!” to the screen for every 7 it sees. Your function must have the following signature: void printSevens(); You do not need to demonstrate calling this function from main().
-Inventory given through picture -Language from C++03 The fill will have the following specifications: Each record consists of two lines. The first line contains the name of the product, which may be more than one word long. The second line contains the wholesale price as a decimal, the markup as a percentage, and three quantities, for counter, shelf, and warehouse. If the first line of a record contains the word END all by itself, that is the end of the file. Your task is to read each record into the program, as a string for the name, and numbers for the price and markup, and as an array of numbers for the quantities. Then calculate the total profit for each item: (wholesale price) * (markup, converted into a decimal) * (total quantity). Print out a report on one line for each item: Name, total profit. Format the output nicely: names should fit in 30 characters and the prices should line up and should have two decimal places. Hints: You’ll want to use getline to read multi-word…
The standard library function int fseek(FILE *fp, long offset, int origin) is identical to Iseek except that fp is a file pointer instead of a file descriptor and the return value is an int status, not a position. Write fseek. Make sure that your fseek coordinates properly with the buffering done for the other functions of the library.
Please help me write the following function (please see the attached photos for context of the problem): find_treasure(start_map_num): Takes an integer between 0 and 9 as input. Loads the corresponding map file, and starts following the trail (at position 0, 0 of that file) as described above. Continues following the trail through other map files as needed. Places an 'X' at the conclusion of the trail and saves the updated treasure map to a new file with 'new_' prepended to the current map filename. Returns a tuple of the row and column index where the 'X' was placed in that file.
What other extended file properties than "cannot be changed" are there to choose from?
With the exception of fp being a file pointer rather than a file descriptor and the return value being an int status rather than a location, the standard library method int fseek(FILE *fp, long offset, int origin) is identical to Iseek. Compose fseek. Ensure that the caching used for the other library functions and your fseek are correctly coordinated.
In this assignment you will be writing several functions that process files and dictionaries to encryptand decrypt messages. A dictionary will be used to create a random substitution cypher. Each letterof the alphabet will be mapped to another random letter in the alphabet. No letter will map or bemapped to any duplicate letter. For example given the partial dictionary below you can encrypt amessage.Be sure to use the starter file provided so you can see the appropriate outputs. Be sure to downloadand place the appropriate text files in the same directory as your python file. You only need to submityour python file.Partial Dictionary: {d : a, e: f, h : b, l : p, l : e, o : j, r: m, w: i}originalMessage = “hello world” → encryptedMessage = “bfeej ijmea” Part 1 - Encrypt a Message: You will write 2 functions to build a dictionary and encrypt a messageFunction buildCypher() → dict:This function is to build a dictionary that can be used to create a random substitution cypher.
