I have a Python function called plot_pdf(f) that might throw an error. I use a list comprehension to iterate over a list of files on this function:

[plot_pdf(f) for f in file_list]

I want to use try-except block to skip any possible errors during the iteration loop and continue with the next file. So is the following code correct way to do the exception handling in Python list comprehension?

try:
    [plot_pdf(f) for f in file_list]  # using list comprehensions
except:
    print ("Exception: ", sys.exc_info()[0])
    continue

Will the above code terminate the current iteration and go to the next iteration? If I can't use list comprehension to catch errors during iteration, then I have to use the normal for loop:

for f in file_list:
    try:
        plot_pdf(f)
    except:
        print("Exception: ", sys.exc_info()[0])
        continue

I want to know if I can use try-except to do exception handling in list comprehension.

try:
    [plot_pdf(f) for f in file_list]  # using list comprehensions
except:
    print ("Exception: ", sys.exc_info()[0])
    continue

If plot_pdf(f) throws an error during execution of comprehension, then, it is caught in the except clause, other items in comprehension won't be evaluated.

It is not possible to handle exceptions in a list comprehension, for a list comprehension is an expression containing other expression, nothing more (i.e. no statements, and only statements can catch/ignore/handle exceptions).

Function calls are expression, and the function bodies can include all the statements you want, so delegating the evaluation of the exception-prone sub-expression to a function, as you've noticed, is one feasible workaround (others, when feasible, are checks on values that might provoke exceptions, as also suggested in other answers).
