The fastest and easiest way to run all Python files in a directory is to use loops. You can use bash to do this for you. For example, create a new file called run_all_py.sh and write the following in it: ,  Now run the file using  ,  You could also use xargs to parallely execute these files(Only available on UNIX). For example, ,

When an arithmetic operation exceeds the limits of the variable type, an OverflowError is raised. Long integers allocate more space as values grow, so they end up raising MemoryError. Floating point exception handling is not standardized, however. Regular integers are converted to long values as needed. Given code is rewritten to catch exception as follows , We get following OverflowError a.....

An IndexError is raised when a sequence reference is out of range. The given code is rewritten as follows to catch the exception and find its type , OUTPUT ,

NameErrors are raised when your code refers to a name that does not exist in the current scope. For example, an unqualified variable name. The given code is rewritten as follows to catch the exception and find its type. , OUTPUT ,

An EOFError is raised when a built-in function like input() or raw_input() do not read any data before encountering the end of their input stream. The file methods like read() return an empty string at the end of the file. The given code is rewritten as follows to catch the EOFError and find its type. , OUTPUT ,

A SyntaxError occurs any time the parser finds source code it does not understand. This can be while importing a module, invoking exec, or calling eval(). Attributes of the exception can be used to find exactly what part of the input text caused the exception. We rewrite the given code to handle the exception and find its type , OUTPUT ,
