Solved in 2 steps
- What type of exception does a program raise when it tries to open a nonexistent file?fname=input("Enter a file's name: ") with open(fname, 'r') as fh: for line in fh: print(line) Criteria to complete the above snippet: 1)Code will keep looping until the user enters an existing file name. 2) need to use exception with [Error 7] as the message 3)need to catch the exception so the program does not crash 4) close the program after reading contents of the file and print contents to the screen 5)create a test fileCreate a program that calculates a five(5) grades of five(5) students and handles exceptions. It reads the data from a file and writes the output to a file. Send a copy of the following: Softcopy of the running code Screenshot of input file and output file Screenshot of the code
- Use files( handling exception)Focus on Basic file operations, exception handling. Save a copy of the file module6data.txt (Below) Write a program that will Open the file module6data.txt Create a second file named processed. txt Read the numbers from the first file one at a time. For each number write into second file, if possible, its Square Square root iii. Reciprocal (1/number)use a math module function for the square root. use exception handling to trap possible errors. Report the number of items in the original file and the number that were successfully stored in the second file. Report the number of each type of error: ValueError, ZeroDivisionError, TypeError 26 O 76 -91 85 -44 85 -95 -34 83 -64 -76 -41 89 0 83 -99 -69 8 -79 0 -32 -49 -89 85 79 -28 56 19 -93 -21 -23 82 51 -80 l 62 -78 -8 71 28 -73 0 -45 -73 28 -5 O -70 63 -36 -72 0 -76 -24 -59 0 -54 83 35 -3 88 -14 29 -35 17 27 -61 -42 49 83 38 79 -80 33 8 41 96 -94 46 71 8 76 -63 -36 93 -82 -68 -20 69 -57 -84 -29 -17 77 36 -89 -94 62 10 -69 -43 Use…Write a sequence of statements to create a file with fileName's name and a line saying "This Is File:" followed by the file's name. Check the file's buffer and system resources consumed by these statements. (Ignore exceptions.)
- Write a program that writes a series of random numbers to a file. Each random number should be in the range 1 through 500. The application should let the user user specify how many random numbers the file will hold. Use an exception to make sure that an integer was typed in by the user for the #to generate. If not reask the user for input in the except clause until they input the correct number. You should do this in one function named mainIf a file is opened for writing but it already contains data, it will append to the file. overwrite the file. delete the file. throw an error.The "-t" flag to "ls" sorts the listing by modification time. Write a BASH line which will write the name of file with the oldest modification time into a file called "lastfile".
- In Python IDLE write a program that writes a series of random numbers to file. Each random number should be in the range of 1 through 500. The application should let the user specify how many random numbers the file will hold This exercise assumes you have completed you have completed program exercise 7 random number file writer. Write another program that reads the random numbers from the file, displayed the numbers, then displays the following data: Exception Handling: Both programs should use Try and Except Clauses to handle IOError, ValueError, and unspecified error exceptions. Be sure to test your programs for invalid cases. For example , try running the second program to read the file when it doesn’t exist or manually put bad data in the file and see what happens.C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.To send an exception, use the _______ keyword. a. finally b. exception c. send d. raise
