I have a requirement to execute multiple Python statements and few of them might fail during execution, even after failing I want the rest of them to be executed.
Currently, I am doing:
try: wx.StaticBox.Destroy() wx.CheckBox.Disable() wx.RadioButton.Enable() except: pass If any one of the statements fails, except will get executed and program exits. But what I need is even though it is failed it should run all three statements.
How can I do this in Python?
Use a for loop over the methods you wish to call, eg:
for f in (wx.StaticBox.Destroy, wx.CheckBox.Disable, wx.RadioButton.Enable): try: f() except Exception: pass Note that we're using except Exception here - that's generally much more likely what you want than a bare except.
If an exception occurs during a try block, the rest of the block is skipped. You should use three separate try clauses for your three separate statements.
Added in response to comment:
Since you apparently want to handle many statements, you could use a wrapper method to check for exceptions:
def mytry(functionname): try: functionname() except Exception: pass Then call the method with the name of your function as input:
mytry(wx.StaticBox.Destroy) 
contextlib.suppress to neaten the code if you're using Python 3.4.mytry seems a bit limited; at the very least, allow it to take the errors to suppress as an argument (the default can still be Exception).I would recommend creating a context manager class that suppress any exception and the exceptions to be logged.
Please look at the code below. Would encourage any improvement to it.
import sys class catch_exception: def __init__(self, raising=True): self.raising = raising def __enter__(self): pass def __exit__(self, type, value, traceback): if issubclass(type, Exception): self.raising = False print ("Type: ", type, " Log me to error log file") return not self.raising def staticBox_destroy(): print("staticBox_destroy") raise TypeError("Passing through") def checkbox_disable(): print("checkbox_disable") raise ValueError("Passing through") def radioButton_enable(): print("radioButton_enable") raise ValueError("Passing through") if __name__ == "__main__": with catch_exception() as cm: staticBox_destroy() with catch_exception() as cm: checkbox_disable() with catch_exception() as cm: radioButton_enable() 
except, at the very least useexcept Exception. 2. If these statements should be executed (or not) independently, put them in separatetryblocks!
