Which of the following statement holds valid with Python for loop?
- initial value is an optional
- stop value is mandatory
- step value is an optional
- none
Answer
stop value is mandatory
Reason — The for loop is a fixed iterative loop where the number of iterations is determined using the range() function. In range(), the initial value and step value are optional because their default values are 0 and 1 respectively, but the stop value is mandatory as it specifies the ending limit of the loop.
