Range Function in Python To perform the increment you have to use the step param with the value you wanted to increment. You could use a while loop and increment i based on the condition: Using a for loop i will always return to the next value in the range: In your example as written i will be reset at each new iteration of the loop (which may seem a little counterintuitive), as seen here: continue is the standard/safe way to skip to the next single iteration of a loop, but it would be far more awkward to chain continues together than to just use a while loop as others suggested. step: integer value which determines the increment between each integer in the sequence Returns: a list Example 1: Incrementing the iterator by 1. Launching the CI/CD and R Collectives and community editing features for What would happen if an airplane climbed beyond its preset cruise altitude that the pilot set in the pressurization system? It is possible to achieve this with a for loop using the send method of a generator, where the counter can be modified if the generator is sent Now inside the while infinite loop there is for and everytime inside for "i" iteration starts over from "0" ideally "i" should get the incremented value and start from 2, output is: So the point is "i" value is not saved and every time loop starts from 0, So how can i make "i" to start from the last incremented value before entering to for loop. else block: The "inner loop" will be executed one time for each iteration of the "outer How to Define an Auto Increment Primary Key in PostgreSQL using Python?
