can i have these code written in python programming langauge. need to import OS to call system fork(), open() etc.

thank you!!!

Questions 1. Write a program that calls fork (). Before calling fork (), have the main process access a variable (e.g., x) and set its value to some- thing (e.g., 100). What value is the variable in the child process? What happens to the variable when both the child and parent change the value of x? 2. Write a program that opens a file (with the open() system call) and then calls fork () to create a new process. Can both the child and parent access the file descriptor returned by open ()? What happens when they are writing to the file concurrently, i.e., at the same time? 3. Write another program using fork(). The child process should print "hello"; the parent process should print "goodbye". You should try to ensure that the child process always prints first; can you do this without calling wait() in the parent
