- What does this regex do?re.compile(r'[ckCK]ath([e]*r[yi]n[e]*|[yi])')What are 6 stings that would match the Regular Expression? Using the regular expression from question 1, write a python script that will take in a string as an argument, and print whetherthe string matches the Regular Expression. So for example, if your script is named "myscript.py", you should be able to run:-python myscript.py Kathyand the script would print a message indicating a match. However, if you run:python myscript.py Bob the script would print a message indicating that there was not a match.Here is my c++ program. I want create a "class" to read string from "data.txt", and output "ok" in another txt "test.txt". But I don't know how to solve the problem. please help me,thanks.Modify the program below to implement exclusive-or (XOR) in Python. AsPython does not natively implement XOR, you will need to implement this by creating an expression using a combination of and, or, and not. Determine what this expression is, and put it in the code below (where “fill in your code here” is written).The starter code below includes the True/True and True/False cases. You should also include the False/True and False/False cases. As a reminder, XOR is only True if exactly one of the inputs is True. Other ways ofthinking about this is that it is True only if one input or the other input is True, but not both. Yet another way of thinking about this is that the result is only True when the inputs are different from each other. SAMPLE STARTER CODE:a = Trueb = Trueresult = # fill in your code hereprint("True XOR True is " + str(result))a = Trueb = Falseresult = # fill in your code hereprint("True XOR False is " + str(result))# Continue for the False/True and False/False…
- Given three int variables that have been given values, areaCode, exchange, and lastFour, write a string expression whose value is the string equivalent of each these variables joined by a single hyphen (-) So if areaCode, exchange, and lastFour, had the values 800, 555, and 1212, the expression's value would be "800-555-1212". Alternatively, if areaCode, exchange, and lastFour, had the values 212, 867 and 5309 the expression's value would be "212-867-5309".Can anyone help me to transfrom the code to PYTHON code? Thanks a lot #include<bits/stdc++.h>using namespace std;void add(string name[],int scores[],string n,int sc){ for(int i=0;i<10;i++) { if(scores[i]<=sc) { for(int j=9;j>i;j--) { name[j]=name[j-1]; scores[j]=scores[j-1]; } name[i]=n; scores[i]=sc; return; } else if(scores[i]==-1) { name[i]=n; scores[i]=sc; return; } }}void print(string name[],int scores[]){ for(int i=0;i<10;i++) { if(scores[i]!=-1) { cout<<name[i]<<" "<<scores[i]<<"\n"; } }}int getHscore(string name[],int scores[],string n){ int ans=-1; for(int i=0;i<10;i++) { if(scores[i]!=-1) {…Three variables, x, y, and z, supposedly hold strings of digits, suitable for converting to integers. Write a code that converts these variables into integers and print sum of the three integers. However, if any variable has a value that cannot be converted to an integer, print out, the string "bad value(s) in:" followed by the names of the variables that have bad values (separated by spaces, in alphabetically ascending order). For example, if the values of x, y, and z were respectively "3", "9", "2" then the number 14 would be printed; but if the values were "abc", "15", "boo" then the output would be: bad value(s) in: x z
- Write a python program which creates and outputs variables of various types. For any lines of code which produce an error, comment out the line and add a comment indicating what the problem is with the line--not only what error message you got, but what it means (explain why). Make sure you do each of the following: set a variable to an Integer value set a variable to a a floating point value create a string using double quotes " which contains both single ' and double " quotes create a string using single quotes ' which contains both single ' and double " quotes create a string using triple single quotes '''' which contains both single ' and double " quotes create a string using triple single quotes """ which contains both single ' and double " quotes use the type conversion functions to convert: integer to float float to string string to integer 2 other type conversions Use the "print" function to output the value of each variable and use the type function to output the data…Given the following code, what is the final value of x? int x=1, y=2, z=3; bool w=true; x=w=y-z;in java Read two strings and two integers from input and call printInfo() to output as follows. Ex: If the input is Rome Suva 2868104 84410, then the output is: Rome has 2868104 people. Suva has 84410 people
- Write a sample Java code that run of the program should look something like output: use the .length(), .substring(), .indexof(), functions in your code. Note: The important thing to note here is that the "4" in input.substring(0,4) is the index of the space character, and the "5" in input.substring(5) is that index plus 1. So we can get the first and last names using: space = input.indexOf(' '); firstName = input.substring(0,space); // Everything before the space lastName = input.substring(space+1); // Everything after the space By the way, this program will only work correctly if the user follows the instructions. If the user's input does not contain a space, then the value of input.indexOf(' ') will be -1, and the -1 will cause the program to crash when used in the substring functionjava You must print the number declared double x; on the screen. With which of the following options do you know that a number in the range -9999.99999 to 9999.99999 is printed with exactly 4 decimals and that all numbers in the number are displayed?
