What is for loop in Python example?
A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.
What is the syntax of for loop in Python?
The for loop uses the syntax: for item in object, where “object” is the iterable over which you want to iterate. Loops allow you to repeat similar operations in your code. One of the most common types of loops in Python is the for loop. This loop executes a block of code until the loop has iterated over an object.
What is for loop explain with example?
A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number. When the number of times is not known before hand, we use a “While” loop.

- Indirect Repetition. for (int value = 1; value <= 3; ++value) { cout << value << endl; }
- Invariants.
- !
- Dependency.
- Separation.
- Half-Open Interval.

The for…of loop Assign it to the variable cat and then run the code between the curly brackets {} . Get the next item, and repeat (2) until you’ve reached the end of the collection.
What is loop explain with example?
