Variables can hold values, and every value has a data type. Python is a dynamically typed language; hence we do not need to define the type of the variable while declaring it. The interpreter implicitly binds the value with its type. Enroll in India’s best online Python course with a certificate and guaranteed job assistance.

Here in this post, you will learn about Python loops. 1. Python has two primitive loop commands: while loops for loops 2. With the while loop we can execute a set of statements as long as a condition is true. 3. With the break statement we can stop the loop even if the while condition is true. 4. With the continue statement we can stop the current iteration, and continue with the next. 5. With the else statement we can run a block of code once when the condition no longer is true.

Python is a beginner-friendly language. It has a simple and easy-to-learn syntax compared to C++ and Java. Here in this post, you will learn about Python basic syntax. Python comments begin with a # or you can also enclosed a multiline comment with triple-quotes '''. Python supports the single quote and the double quote for string literals. If you leave a line with just whitespace, the interpreter will ignore it.

A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. Similarly to while loop, a for loop can also use the key words: break, continue, else. To loop through a set of code a specified number of times, we can use the range() function.

Here in this post, you will learn about Python functions. 1. In Python a function is defined using the def keyword. 2. To call a function, use the function name followed by parenthesis.

1. Dictionaries are used to store data values in key:value pairs. 2. Dictionaries are written with curly brackets, and have keys and values. 3. Dictionary items are ordered, changeable, and does not allow duplicates.

Here in this post, you will learn about Python collections. 1. Collections in python are basically container data types, namely lists, sets, tuples, dictionary. 2. Lists are used to store multiple items in a single variable. 3. Lists are created using square brackets. 4. List items are ordered, changeable, and allow duplicate values.
