Pressing buttons and navigating on site pop-ups (e.g.() gives the current datetime’s epoch time) timestamp() on a datetime object to get the epoch timestamp (a) You can use () to get the current date and time Also use the datetime module an create an extra column that keeps track of the time the.os.path.isfile(”test/rt.txt”) checks if the file rt.txt exists in the folder test (relative to the folder where the program is saved). (a) You can use os.path.isfile(pathToFile) to check if the file at the location referencedĮ.g. You can use the os module to check if a specific file exists.(c) You can use time.sleep(seconds) to make your program wait for a specific number of The time difference between the event and now) Occurred and reference it later (or subtract it from calling time.time() again to get (b) You can store time.time() in a variable to keep track of the time that an event (a) You can use time.time() to get the current epoch time ![]() You can use the time module to get the current time and also have your program wait.Make this webscrap run every 15 seconds, and make sure to not overwrite your previous data file. Good/appropriate for further analysis) and save it to a csv file. The list of S&P 500 companies for the ticker symbols, and gets the additional information fromįurthermore, put this data into a pandas dataframe (in whatever format you think is Modify the programs we’ve created in the previous lecture to have a program that scraps Time to combine these information sources.
