What does a search warrant actually look like? 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. There are multiple ways to iterate over a list in Python. for loop runs for i=0 to i=9, each time initializing i with the value 0 to 9. when i = 3, above condition executes, does the operation i=i+1 and then continue, which looks to be confusing you, so what continue does is it will jump the execution to start the next iteration without executing the code after it in the loop, i.e. Don't overwrite variable i in the for loop (I changed that to _): Thanks for contributing an answer to Stack Overflow!
