What are the functions of the zip function in Python?
The function of the zip function in Python includes:
- Pack the corresponding elements of multiple iterable objects into tuples and return a new iterable object.
- If the lengths of the input iterable objects are not the same, the zip function will use the shortest iterable object as a reference, and any extra elements will be ignored.
- The zip function can take any number of iterable objects as parameters and pack their corresponding elements into tuples.
- You can use the form zip(*iterables) to pass in multiple iterable objects and unzip their corresponding elements into multiple tuples.
- The zip function is commonly used for parallel iteration, allowing for simultaneous traversal of corresponding elements in multiple iterable objects.
- You can convert the iterable object returned by the zip function to a list using list(zip(iterable1, iterable2)).
- You can use dict(zip(keys, values)) to pack corresponding elements of two iterable objects into a dictionary.
- You can convert the iterable object returned by the zip function into a set using set(zip(iterable1, iterable2)).
- The zip_longest() function can be used to handle situations where the length of iterable objects is not consistent during parallel iteration. The fillvalue parameter specifies the value to be filled when the iterable objects are not sufficient in length.
