To measure time elapsed during program's execution, either use time.clock() or time.time() functions. The python docs state that this function should be used for benchmarking purposes. exampleimport time t0= time.clock() print("Hello") t1 = time.clock() - t0 print("Time elapsed: ", t1) # CPU seconds elapsed (floating point)OutputThis will give the output −Time elapsed:  1.2999999999999123e-05You can also use the time module to get proper statistical analysis of a code snippet's execution time.  It runs the snippet multiple times and then it tells you how long the shortest run took. You can use it as follows:Exampledef f(x):   return x * x ... Read More

% can either take a variable or a tuple. So you'd have to be very explicit about what you want it to do. For example, if you try formatting such that −Examplemy_tuple = (1, 2, 3) "My tuple: %s" % my_tuple You'd expect it to give the output: My tuple: (1, 2, 3)OutputBut it will throw a TypeError. To guarantee that it always prints, you'd need to provide it as a single argument tuple as follows −"hi there %s" % (name, )   # supply the single argument as a single-item tupleRemembering such caveats every time is not that easy ...

To measure time of a program's execution, either use time.clock() or time.time() functions. The python docs state that this function should be used for benchmarking purposes. exampleimport time t0= time.clock() print("Hello") t1 = time.clock() - t0 print("Time elapsed: ", t1 - t0) # CPU seconds elapsed (floating point)OutputThis will give the output −Time elapsed:  0.0009403145040156798You can also use the timeit module to get proper statistical analysis of a code snippet's execution time.  It runs the snippet multiple times and then it tells you how long the shortest run took. You can use it as follows:Exampledef f(x):   return x * x ... Read More

To find out if 24 hrs have passed between datetimes in Python, you will need to do some date math in Python. So if you have 2 datetime objects, you'll have to subtract them and then take the timedelta object you get as a result and use if for comparision. You can't directly compare it to int, so you'll need to first extract the seconds from it. examplefrom datetime import datetime NUMBER_OF_SECONDS = 86400 # seconds in 24 hours first = datetime(2017, 10, 10) second = datetime(2017, 10, 12) if (first - second).total_seconds() > NUMBER_OF_SECONDS:   print("its been over a day!")OutputThis ...

Python provides different ways to find the execution time taken by a script or specific parts of the code such as using the functions from the time module, like time.time() or time.clock(). The following are some common methods used to measure execution time in Python: Using time.time() Function Using time.process_time() Function Using timeit Module Getting Program Execution Time Using time.time() Function The time.time() function returns the current time as a floating-point number that indicates the seconds elapsed since the epoch (when time began). To calculate the execution time ... Read More

Python provides various modules, such as time, datetime, and timeit, to measure time with high accuracy. These modules offer high-resolution clocks to measure time intervals. The following are several methods used to measure time with high precision in Python. Using time.time() Method Using time.perf_counter() Function Using timeit.default_timer() Using time.time() Method for Simple Timing The time.time() method returns the current time in seconds since the epoch as a floating-point number. The epoch is system-dependent, but on Unix-like systems, it is typically January 1, 1970, 00:00:00 (UTC). ... Read More

We can use the PyMongo library (the official Mongodb driver for Python) to connect to a Mongodb database and use it to insert, update, delete, etc objects. To include date and time information, Mongodb supports ISODate format, and PyMongo provides direct support for Python's datetime.datetime objects. There are multiple ways to prepare a Python date object for insertion into MongoDB, which we will discuss here: Create and Insert Date Object to MongoDB Using datetime.datetime.utcnow() The simplest way to create a Python date object that can be inserted into MongoDB is by using datetime.datetime.utcnow() from the datetime module. You can use ... Read More

You can use the fromtimestamp() function from the datetime module to get a date from a UNIX timestamp. This function takes the timestamp as input and returns the datetime object corresponding to the timestamp.  Exmaple import datetime timestamp = datetime.datetime.fromtimestamp(1500000000) print(timestamp.strftime('%Y-%m-%d %H:%M:%S'))OutputThis will give the output −2017-07-14 08:10:00

Two commonly used functions from the Python time module are time.time() and time.clock(). Each function provides a different purpose and returns different values depending on the platform (Windows vs. Unix). In Python 3.8, time.clock() was removed, so time.perf_counter() or time.process_time() are generally preferred over the older time.clock() for specific CPU time measurements. The time.clock() was designed for measuring process CPU time, while time.time() measures wall-clock time. The time.time() is more accurate for measuring overall elapsed time ( the duration of time that has passed between two specific points in time). Measuring Elapsed Time with time.time() The time.time() function returns the number of ... Read More

 While working with Python regex,  if we want to match everything except certain characters, then we can use negated character classes by placing a caret (^) as the first character inside square brackets. The pattern [^abdfgh] will match any character not in that set. What is a Negated Character Class? A character class like [abc] matches any single character except 'a', 'b', or 'c'. But if we use a ^ symbol at the beginning, like [abc], it will match any character except 'a', 'b', or 'c'. This allows us to eliminate certain characters from the match quickly. The position of ...
