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 …
Overview of Boolean Type¶ Let us get into the details related to Boolean. Boolean typically will have True or False. In Python it is defined as bool. You can assign boolean value by saying a = True or a = False. All comparison operators which we will be seeing as part of the next topic …
