Hello!
I am trying to write a program in Pynthon.
Need help.
Requirements:
Write a .py file like KevFiles.py (I used Spyder to do this).
In that .py, create a function that strips the first letters from all file names in a directory. If the new name is a duplicate of an existing name, Python will throw an exception. Handle that exception by adding “dup” a number as part of the files new name.
Call that function from a Jupyter Notebook, passing in the number of characters to delete and the file path.
Thank you!
Expert Answer
Program Plan:
- Import required packages
- Prompt the path and the number of characters to delete from the user.
- Call the method “proc_file” by passing the arguments
- Define the method “proc_file()”
- Get the list of file name.
- Initialize the counter value to “1”.
- Get the file name from the directory
- Generate new files
- Add “dup” and count when the same filename exists
- Add “dup” with the file name if the condition is “true”.
- Increment the counter value.
- Otherwise, append the file name
- Print the file names.
- Check for any exception in the file.
- Print the exception
- Call the main function
File Name: a.py
#Import required package
import os
#Main function
def main():
#promt the path of a directory
print('Enter file directory: ')
path = input()
#Prompt number of characters to delete
print('Enter the number of characters to delete? ')
charDel = int(input())
#Call the method proc_file
proc_file(charDel, path)
#Definition of method proc_file
def proc_file(char_del, path):
#Get the list of file names
names = list()
inc = 1
try:
# Getting file name from the directory
for each_file in os.listdir(path):
# Generating new file
new_fname = each_file[char_del:]
# Adding dup and count when the same filename exists
if new_fname in names:
new_fname += '_dup' + str(inc)
inc += 1
else:
#Appending the file names
names.append(new_fname)
#Print the file names
print(new_fname)
#Throw the error message
except Exception as e:
#Print the error message
print(str(e))
#Call the main function
if __name__=='__main__':
main()
