In this example, you will learn to catch multiple Python exceptions in one line.
To understand this example, you should have the knowledge of the following Python programming topics:
- Python Input, Output and Import
- Python Errors and Built-in Exceptions
- Python Exception Handling Using try, except and finally statement
Multiple exceptions can be caught using a tuple. The errors can be passed through a tuple as shown in example below.
Multiple exceptions as a parenthesized tuple
string = input()
try:
num = int(input())
print(string+num)
except (TypeError, ValueError) as e:
print(e)
Input
a 2
Output
can only concatenate str (not "int") to str
Here, we try to catch two types of exceptions TypeError and ValueError, which are passed as inside a tuple in the except block.
In the above example, string and an integer cannot be added, so TypeError is caught.
Let’s see another example with a different exception.
Input
a b
Output
invalid literal for int() with base 10: 'b'
In the above example, the second input should have been an integer, but we passed a string 'b'. Therefore, ValueError is raised.
Note: The error which comes first is caught as an exception in case of multiple exceptions.
