Python try without except

Use the pass statement to use a try block without except in Python. A pass is just a placeholder for nothing, it just passes along to prevent SyntaxErrors.

try:
  doSomething()
except: 
  pass

The pass statement does nothing and it is used when a statement is required syntactically but the program requires no action.

Python try without except

Simple example code using try without except (ignoring exceptions) in Python.

my_list = []

try:
    # ValueError
    my_list.remove(1)
except:
    # this runs
    print(my_list)
    pass

Output:

If you have to specify multiple exception classes, make sure to wrap them in parentheses.

If you’re confident that your block won’t raise an exception, you could just remove the try block altogether

for i in lines:
    print(i[3])

How to properly ignore exceptions

try:
    doSomething()
except Exception: 
    pass

or

try:
    doSomething()
except: 
    pass

The difference is that the second one will also catch KeyboardInterrupt, SystemExit and stuff like that, which are derived directly from BaseException, not Exception.
