UnlikeJava, In Python we can have an optional ‘else’ block associated with the loop. The ‘else’ block executes only when the loop has completed all the iterations. Lets take an example: forvalinrange(5):prin
In Python, we use awhileloop to repeat a block of code until a certain condition is met. For example, number =1whilenumber <=3:print(number) number = number +1 Output 1 2 3 In the above example, we have used awhileloop to print the numbers from1to3. The loop runs as long as ...
For example, languages = ['Swift', 'Python', 'Go'] # start of the loop for lang in languages: print(lang) print('---') # end of the for loop print('Last statement') Run Code Output Swift --- Python --- Go --- Last statement Here, print('Last statement') is outside the...
Pythonrange()function is used to generate a sequence of numbers within a given range. You can use the range() function with a negative step value to implement the loop iterations from in backside rather than the front side. For example, # Get the for loop in backwards using range() print...
Example 1:Let’s specify only the stop parameter in the range() function. # range() with stop parameter i=0 while i in range(10): print(i,end=" ") i=i+1 # Output: # 0 1 2 3 4 5 6 7 8 9 Here, we specified stop as 10. So it will return the values starting from 0 ...
First, we will start this while loop tutorial by introducing its basics, key features, and syntax, and then we will proceed to its overall working with practical examples, and advanced concepts like state machines, exception handling, and file handling using while loops in Python. By the end ...
In Python, there is no native ___ loop, but we can emulate it using a while loop with a condition at the end. To emulate a do-while loop, you can place the loop’s body inside a ___ block and then check the condition at the end of the loop. In order to ensure the loop...
Example: do...while loop in C #include<stdio.h>intmain(){inti =0;do{printf("%d\n", i+1); i++; }while(i <10);return0; } Run Code >> The above code prints numbers from 1 to 10 using thedo whileloop in C. It prints 1 before checking ifiless than 10. ...
In Ruby,for loopis implemented with the help of the following syntax: for variable_name[, variable...] in expression [do] # code to be executed end Example 1 =beginRuby program to print the table of the numberspecified by the user using for loop=endputs"Enter a number:"num=gets.chomp...
File Objects: Files in Python can be iterated over line by line. This feature is particularly useful for reading large files without loading the entire file into memory. with open('example.txt', 'r') as file: for line in file:
