The file akaroawindgusts.txt contains hourly maximum wind gusts speeds at the Akaroa Electronic weather station (Ews) through February 2014. Inspect it in any halfway decent text editor (not Microsoft Notepad, but Wing will do) so you can see which column contains the wind speed data, how many rows to skip, and what the column separator (delimiter) is. Then write a function plot_ wind gust histogram(filename) that reads a file in that format and plots a histogram of the peak wind gust speeds. The graph you get should look like the one below. Wind gusts from akaroawindgusts.txt 250 200 150 100 50 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 Wind gust speed (km/h) Notes: • The bins are all 10 km/h wide, starting at 0 10 and finishing at 130 - 140. You must set these bins explicitly. • It is not a density plot - the vertical axis displays a count of how many records were in each bin. • You will have to explicitly set x ticks every 10 km/h. • Your function is not permitted to use any…

Problem Definition Task. Your task is to develop a python program that reads input from text file and finds if the alphanumeric sequence in each line of the provided input file is valid for Omani car license plate. The rules for valid sequences for car plates in Oman are as follows: Each sequence is composed of 1 to 5 digits followed by one or two letters. Digits cannot start with 0, for instance, 00, 011, or 09 are not valid digit sequences. The following list are the only valid letter combinations: ['A','AA','AB','AD','AR','AM','AW",'AY"', 'B', BA','BB','BD',"BR','BM',"BW',"BY', 'D','DA','DD','DR','DW','DY', 'R','RA','RR','RM','RW','RY', 'S','SS', 'M','MA','MB','MM','MW','MY", "W',"WA',WB',"wW', Y,YA','YB','YD','YR','YW',YY] Program Input/Output. Your program should read input from a file named plates.txt and write lines with valid sequences to a file named valid.txt. Any line from the input file containing invalid sequence should be written to a file named invalid.txt. Each line…
Write a program that reads in a line consisting of a students name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1.

Use Python 3 for this question. Do the sentiment analysis based on a text file which contains numerous tweets in its raw text format. All tweets collected in this file contains a key word specified by the instructor. The key word being used is “Trump”. You can use the raw tweets file provided by the following link: tinyurl.com/46ntt3a5. You will need to convert this to a .txt file for this assignment. Your raw tweets file size at least needs to be 350K. After you have the raw tweets file ready, you need to perform the following tasks in a Jupyter notebook file. First you need to clean up the tweet file content to the best you can. For each word that is not a “stop word” (and, the, a, is, as, …), assign a value +1 for positive sentiment or a value -1 for negative sentiment. A list of “positive” words will be provided to you. You can easily find a list of “stop words”, and a list of “negative” words online. For the words that is not in positive/negative/stop words, count as ‘others’.…
Can you write a new code in C language with the values I sent you, just like this output? There are two files named group1.txt and group2.txt that contain course information and grades of each student for each class. I will calculate each course average for each group and show in simple bar graph. Use "*" and "#"characters for group1 and group2, respectively. I will see the number -999 at the end of each line in the input files. This value is used for line termination and you can use it to verify that you have arrived at the end of the line. The averages of each group should also be calculated and printed at the end of the file.

In the input file (see image), grades are listed for the geography tests of group 2b. There have been three tests of which the grades will be included in the half-yearly report that is given to the students before the Christmas break. On each line of the input you can find the name of the student, followed by one or more under scores (’_’). These are succeeded by the grades for the tests, for example: Anne Adema____________6.5 5.5 4.5Bea de Bruin__________6.7 7.2 7.7Chris Cohen___________6.8 7.8 7.3Dirk Dirksen__________1.0 5.0 7.7 The lowest grade possible is a 1, the highest a 10. If somebody missed a test, the grade on the list is a 1. The assignment is to make the report for the geography course of group 2b, which should look like this: Report for group 2bAnne Adema has an average grade of 5.5Bea de Bruin has an average grade of 7.2Chris Cohen has an average grade of 7.3Dirk Dirksen has an average grade of 4.6End of report Use functions to structure the code in Python.

Do not read directly from the example files, as the automated testing system expects you to read from the standard input. Instead, process the lines as follows: In the input file, grades are listed for the geography tests of group 2b.

Implement the Function has_error Implement the function according to the specification. Use the test script testcurrency.py to aid your development before checking your answer below. CANNOT USE IF/CONDITIONAL STATEMENTS Instead, you should use what you know about boolean expressions def has_error(json):"""Returns True if the response to a currency query encountered an error. Given a JSON string provided by the web service, this function returns True if thequery failed and there is an error message. For example, if the json is '{"success":false,"src":"","dst":"","error":"Source currency code is invalid."}' then this function returns True (It does NOT return the error message'Source currency code is invalid'). On the other hand if the json is '{"success": true, "src": "2 United States Dollars", "dst": "1.772814 Euros", "error": ""}' then this function returns False.
