4 paź 2015 · If you want to iterate over the indexes of items in your list, use for in range(..): >>> for i in range(len(original_list)): ... if original_list[i] < 0: ... ... Alternatively, you might also want to use enumerate() if you need both item and index in loop's body: >>> for i, item in enumerate(original_list):
31 mar 2023 · The for i in range(len(x)) syntax is used when you encounter unique cases that require you to modify the original list or you want to access more than just the current item in the iteration. Most of the time, the syntax can be replaced with the enumerate() function, which also handles cases where you need more than just the item inside the ...
The Python range() function simply returns or generates a list of integers from some lower bound (zero, by default) up to (but not including) some upper bound, possibly in increments (steps) of some other number (one, by default). So range(5) returns (or possibly generates) a sequence: 0, 1, 2, 3, 4 (up to but not including the upper bound).
result = 0 n = 5 for i in range(1, n + 1): result += i # to ^ ^ jest skrótem dla # wynik = wynik + i print(result) Należy zwrócić uwagę, że maksymalna wartość w przedziale () jest n + 1 , aby i wynosi n w ostatnim kroku.
