Python: Input a filename and print the extension of that

Python Basic: Exercise-7 with Solution

Write a Python program to accept a filename from the user and print the extension of that.

Sample filename: abc.java

Python str.rsplit(sep=None, maxsplit=-1) function:

The function returns a list of the words of a given string using a separator as the delimiter string.

• If maxsplit is given, the list will have at most maxsplit+1 elements.
• If maxsplit is not specified or -1, then there is no limit on the number of splits.
• If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings.
• The sep argument may consist of multiple characters.
• Splitting an empty string with a specified separator returns [''].

Sample Solution:-

filename = input("Input the Filename: ")

f_extns = filename.split(".")

print ("The extension of the file is : " + repr(f_extns[-1]))

========= RESTART: F:/Python_APSC/py-ex-basic-7.py ============

Input the Filename: ex3-1.py

The extension of the file is : 'py'
