usecols CSV: Only store the columns which are need so that a subset of columns is returned, resulting in much faster parsing time and lower memory usage. code.
usecols CSV: skip column. code. code. code. code.

unique() CSV: (code) (code)
.text() (code)
watchdog.utils.bricks.SkipRepeatsQueue Thread-safe event queue based on a special queue that skips adding the same event (FileSystemEvent) multiple times consecutively. Thus avoiding dispatching multiple event handling calls when multiple identical events are produced quicker than an observer can consume them.
watchdog.utils.BaseThread Producer thread base class subclassed by event emitters that generate events and populate a queue with them.
Parameters: event_queue (watchdog.events.EventQueue) – The event queue to populate with generated events.
watch (ObservedWatch) – The watch to observe and produce events for.
timeout (float) – Timeout (in seconds) between successive attempts at reading events.
watchdog.utils.BaseThread Consumer thread base class subclassed by event observer threads that dispatch events from an event queue to appropriate event handlers.
Parameters: timeout (float) – Event queue blocking timeout (in seconds).

unschedule(watch)

 Unschedules a watch.
Parameters: watch (An instance of ObservedWatch or a subclass of ObservedWatch) – The watch to unschedule.
unschedule_all() Unschedules all watches and detaches all associated event handlers.
class watchdog.utils.BaseThread
class watchdog.utils.dirsnapshot.DirectorySnapshot(path, recursive=True, walker_callback=<function <lambda> at 0x7f78fbeed500>, stat=<built-in function stat>, listdir=<built-in function listdir>) A snapshot of stat information of files in a directory.
Parameters:
path (str) – The directory path for which a snapshot should be taken.
recursive (bool) – True if the entire directory tree should be included in the snapshot; False otherwise.
walker_callback –
Deprecated since version 0.7.2.
stat –
Use custom stat function that returns a stat structure for path. Currently only st_dev, st_ino, st_mode and st_mtime are needed.
A function with the signature walker_callback(path, stat_info) which will be called for every entry in the directory tree.
listdir – Use custom listdir function. See os.listdir for details.

class watchdog.utils.dirsnapshot.DirectorySnapshotDiff(ref, snapshot)

Compares two directory snapshots and creates an object that represents the difference between the two snapshots.
Parameters:
ref (DirectorySnapshot) – The reference directory snapshot.
snapshot (DirectorySnapshot) – The directory snapshot which will be compared with the reference snapshot.
upper() Returns the string by converting all the characters of the string to upper case. code. code.
urllib urllib is a package that collects several modules for working with URLs:
         urllib.error containing the exceptions raised by urllib.request
         urllib.parse for parsing URLs
         urllib.robotparser for parsing robots.txt files
urllib.request Defines functions and classes that help to open the URL (for opening and reading URLs/www webpages). Introduction. code.
urlretrieve Is used for retrieving the files, and the URL is assigned.
use_index Use the object index for tick labels
Count duplicates/occurrence and show unique values in csv files CSV: Introduction
hotkey('up') Introduction
hotkey('u') Introduction
.mouseUp() Move the mouse and then release it. .mouseUp(x=moveToX, y=moveToY, button='left'). .click() function is just a convenient wrapper around these two .mouseDown() and .mouseUp() function calls. (code)
random.uniform() (code).
