Overview of Exception Handling¶ Let us get an overview of Exception Handling. Exception Handling in general means dealing with unexpected events (eg: trying to add a number with string). Here are the different ways using which we handle exceptions in Python. Using try catch blocks. Throwing or raising exceptions as part of if conditions. Using …
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. …
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] …
Conditionals¶ Let us go through conditionals in Python. We typically use “if else” for conditionals. Let us perform a few tasks to understand how conditionals are developed.* Create a variable i with 5. Write a conditional to print whether i is even or odd. In [1]: i = 5 In [2]: # Regular if else if i …
Comments and Doc Strings¶ Let us understand how we can add doc strings and comments in Python. We use doc strings to provide instructions to use a function. Doc strings are provided immediately after function name. We can specify it as standard Python string. People typically enclose doc string with in 3 quotes (single or …
Operators in Python¶ As any programming language Python supports all types of Operations. There are several categories of operators. For now we will cover Arithmetic and Comparison Operators.* Arithmetic Operators Addition (+) Subtraction (-) Multiplication (*) Division (/) Mod (%) returns reminder + is also used for concatenation of strings. Comparison Operators – typically return …
