When it comes to class hierarchy in Python, Exception is the root class. All unhandled exceptions can be dealt with Exception as part of …
Exception Handling – else and finally¶ Let us go through else and finally. Some times we might want to log all sucessful executions. We can leverage else for it. If no exceptions are raised or thrown, then the code in else block will be executed. The code in the finally will be executed all the …

eval and exec¶ Let us understand how we can use eval and exec in Python. Typically we perform arithmetic operations like this a = b + c. We can also use eval and exec for the same. eval typically evaluates the expression. We need to assign the value to some variable when we use eval. …
Running OS Commands¶ Let us understand how to run OS commands using Python using libraries such as os and subprocess.* Python provides several libraries which can be used to run OS commands. os and subprocess are most popular ones. We can import the libraries such as os and subprocess to start using them. There are …
All about for Loops¶ Let us understand how we can loop through using for in Python.* Go through range between 2 integers (5 and 10) and print them. We can use range function to get range between two integers. In [1]: range(5, 11) Out[1]: range(5, 11) In [2]: list(range(5, 11)) Out[2]: [5, 6, 7, 8, 9, 10] …
