In Python, therange()function returns a sequence of numbers. For example, # generate numbers from 0 to 3values = range(0,4) Here,range(0, 4)returns a sequence of0,1,2,and3. Since therange()function returns a sequence of numbers, we can iterate over it using aforloop. For example...

Python range() returns the sequence of numbers starting from a given start integer to a stop integer, which we can iterate using a for loop
Python Nested for Loop In Python, thefor loopis used to iterate over a sequence such as alist, string,tuple, other iterable objects such as range. Syntax of using a nested for loop in Python # outer for loopforelementinsequence# inner for loopforelementinsequence: ...
You'll also learn the difference between using a while loop and a for loop. Also the topic of nested loops After, you'll see how you can use the break and continue keywords. The difference between the xrange() and range() functions While Loop The while loop is one of the first loop...
In all our previous examples we have used index variable to process the loop element. Now if we don't want to use the index variable then you can use therange()in following way: num = 5 for _ in range(num): print("This will run n number of times the elements present in num") ...
Python for loop vs while loop Thefor loopis usually used in the sequence when the number of iterations is known. For example, # loop is iterated 4 timesforiinrange(4):print(i) Run Code Output 0 1 2 3 Thewhileloop is usually used when the number of iterations is unknown. For example...
