When dealing with multiple conditions that need to be evaluated, Python’sif-elif-elsestructure is particularly useful. Theelifclause (short for “else if”) allows you to specify additional conditions to check if the initialifcondition is not met. This enables a more structured and efficient way...
In this tutorial, I will explain how touse Tkinter Entry widget in Pythonto accept user input in your GUI applications. The Entry widget allows users to enter and display a single line of text. I’ll explain several examples using common American names to demonstrate how to create, customize...
logical operators such as OR, AND, and NOT return the Boolean value “True or False”. These operators help us to combine multiple decisions-driven statements. Logical operators are used along with conditions like “if”, “if-else”, and “elif” to reduce multiple lines...
To create scripts and modules, you can use a code editor or an integrated development environment (IDE), which are the second and third approaches to coding in Python. REPLs (Read-Evaluate-Print Loops) Although you can create functions in an interactive session, you’ll typically use the ...
Switch Case in Python With User Input Using if-elif-else In programming terms, we can also use if-elif-else, also known as the if-else ladder. Here, we can take user input and check that input with every condition individually.
evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif. Theelifor else if statement looks like theifstatement and will evaluate another condition....
While using binary files, we have to use the same modes with the letter‘b’at the end. So that Python can understand that we are interacting with binary files. ‘wb’ –Open a file for write only mode in the binary format. ‘rb’ –Open a file for the read-only mode in the bina...
The two groups are the user string and the message. The.groups()method returns them as a tuple of strings. In thesanitize_message()function, you first use unpacking to assign the two strings to variables: Python defsanitize_message(match):user,message=match.groups()returnf"{censor_users(us...
The elif statementWe can create multiple branches using the elif keyword. It tests for another condition if and only if the previous condition was not met. Note that we can use multiple elif keywords in our tests. main.py #!/usr/bin/python import random r = random.randint(-5, 5) ...
When used in overloading, such functions are called factory methods. We can use them to implement the concept of constructor overloading in Python. Example: classdelftstack(object):def__init__(self,a):self.ans="a"@classmethoddeffirst(cls):return"first"@classmethoddefsecond(cls):return"secon...
