How to combine two Python Try Exceptions?

You can combine two or more try-except blocks in Python by nesting them inside each other. Here’s an example:

try:
    # code that might raise an exception
    f = open('myfile.txt')
    try:
        # code that might raise another exception
        s = f.readline()
        i = int(s.strip())
    except ValueError:
        # code to handle the ValueError exception
        print("Error: invalid integer in file")
    finally:
        # code that always executes, whether an exception was raised or not
        f.close()
except FileNotFoundError:
    # code to handle the FileNotFoundError exception
    print("Error: file not found")

In this example, the outer try-except block catches a FileNotFoundError exception if the file 'myfile.txt' does not exist. The inner try-except block catches a ValueError exception if the file contains an invalid integer. The finally block is used to close the file, whether an exception was raised or not.

Note that you can nest try-except blocks as deeply as you need to, although it’s generally a good idea to keep the code as simple and readable as possible. Also, be aware that catching multiple exceptions in the same except block can make the code harder to read and maintain, so it’s usually better to handle different exceptions separately if possible.
