Send SMS updates to mobile phone using python
In this tutorial, we are going to learn how to send SMS in Python. We will be using Twilio for sending SMS.First of all, go the Twilio and create an account. You will get free trial account. And finish settings.We have to install a module called twilio to work with Twilio client. Install it with the following command.pip install twilioNow, go to the Twilio Documentation on how to send SMS using Twilio client. Or follow the steps to send the SMS.Import the twilio Client from twilio.rest.Get and store the account_sid and auth_token from the your Twilio account.Make instance of the ...
Read MorePython Grouped Flattening of list
In this tutorial, we are going to write a program that flattens a list that contains sub-lists. Given number flatten the sublists until the given number index as parts. Let's see an example to understand it clearly.Inputlists = [[1, 2], [3, 4], [5, 6], [7, 8], [9, 10]] number = 2Output[[1, 2, 3, 4], [5, 6, 7, 8], [9, 10]]Let's see the steps to solve the problem.Initialize the list and number.Initialize an empty list.Iterate over the list with range(0, len(lists), number.Get the sublists using slicing lists[i:number].Iterate over the sublists and append the resultant list to the result list.Print the result.Example# ...
Read MoreMathematical Functions in Python - Special Functions and Constants
In this article, we will learn about special functions and constants available in the math module in the Python Standard Library.Here we will discuss some constants like −pieinfNantauAnd some functions likeGammaIsinfIsnanisfinite()erf()Let's discuss constants and their respective values −pi3.141592…..e2.718281…...inf6.283185…...nantauNow let’s discuss some special functions and their implementation −Gamma − return the value of gamma(n)Isinf − checks whether the value of the function is infinity or not.Isnan − check whether the return value is a number or not.Isfinite − return True if the value is neither an infinity or a nan false otherwiseErf − returns the error function of x.Now let;’s take ...
Read MoreIntersection() function Python
In this article, we will learn about intersection() function that can be performed on any given set. According to mathematics intersection means finding out common elements from the two sets.Syntax.intersection( ……..)Return Value common elements in sets passed as arguments.Exampleset_1 = {'t', 'u', 't', 'o', 'r', 'i', 'a', 'l'} set_2 = {'p', 'o', 'i', 'n', 't'} set_3 = {'t', 'u', 't'} #intersection of two sets print("set1 intersection set2 : ", set_1.intersection(set_2)) # intersection of three sets print("set1 intersection set2 intersection set3 :", set_1.intersection(set_2, set_3))Outputset1 intersection set2 : {'i', 'o', 't'} set1 intersection set2 intersection set3 : {'t'}Explanation Here a search is made ...
Read Moreisupper(), islower(), lower(), upper() in Python and their applications
In this article, we will learn about isupper(), islower() ,upper() , lower() function in Python 3.x. or earlier.These are the functions that can be used on strings and related types. They are included in Python Standard Library.All the functions accept no arguments. The isupper() & islower() return boolean values whereas the upper() & lower() function returns strings either in uppercase or lowercase.Now let’s see the implementation using an exampleExamplestring = 'tutorialspoint' # checking for uppercase characters print(string.isupper()) # checking for lowercase characters print(string.islower()) # convert to uppercase characters print(string.upper()) # convert to lowercase characters print(string.lower())OutputFalse True ...
Read MoreYouTube Media/Audio Download using Python - pafy
In this article, we will see how to extract details about Youtube videos and download them in different formats using the pafy module. Head over to the link for official documentation.Install the pafy module using the following commandpip install pafyIf you run the above command, it will generate the following results on the successful installation of the module pafy.Collecting pafy Using cached https://files.pythonhosted.org/packages/b0/e8/3516f761558525b00d3eaf73744eed5c267db 20650b7b660674547e3e506/pafy-0.5.4-py2.py3-none-any.whl Installing collected packages: pafy Successfully installed pafy-0.5.4Check whether you can import the pafy module or not by running the following command.import pafyIf you found no errors then it's done. Otherwise install the following module to solve ...
Read MoreBinary Search (bisect) in Python
Here we will see the bisect in Python. The bisect is used for binary search. The binary search technique is used to find elements in sorted list. The bisect is one library function.We will see three different task using bisect in Python.Finding first occurrence of an elementThe bisect.bisect_left(a, x, lo = 0, hi = len(a)) this function is used to return the left most insertion point of x in a sorted list. Last two parameters are optional in this case. These two are used to search in sublist.Examplefrom bisect import bisect_left def BinSearch(a, x): i = bisect_left(a, x) ...
Read MoreList Methods in Python - in, not in, len(), min(), max()
In this article, we will learn about various types of list methods available to us in Python 3.x. Or earlier. These operators allow us to perform the basic operations on the list content.In & Not in operators“in” operator − This operator is used to check whether an element is present in the passed list or not. Returns true if the element is present in the list otherwise returns false.“not in” operator − This operator is used to check whether an element is not present in the passed list or not. Returns true if the element is not present in the ...
Read MoreIterate over a dictionary in Python
In this article, we will learn about iteration/traversal of a dictionary in Python 3.x. Or earlier.A dictionary is an unordered sequence of key-value pairs. Indices can be of any immutable type and are called keys. This is also specified within curly braces.Method 1 − Using iterables directlyExampledict_inp = {'t':'u', 't':'o', 'r':'i', 'a':'l', 's':'p', 'o':'i', 'n':'t'} # Iterate over the string for value in dict_inp: print(value, end='')OutputtrasonMethod 2 − Using iterables for values of the dictionaryExampledict_inp = {'t':'u', 't':'o', 'r':'i', 'a':'l', 's':'p', 'o':'i', 'n':'t'} # Iterate over the string for value in dict_inp.values(): print(value, end='')OutputoilpitMethod 3 − ...
Read MoreIterate over characters of a string in Python
In this article, we will learn about iterating/ traversing over characters of a string in Python 3.x. Or earlier.The string is a collection of characters which may contain spaces, alphabets or integers. They can be accessed using indexes or via references . Some commonly implemented methods are shown below.Method 1 − The direct itertor without indexingExamplestring_inp = "tutorialspoint" # Iterate over the string for value in string_inp: print(value, end='')Method 2 − The most common way using index based accessExamplestring_inp = "tutorialspoint" # Iterate over the string for value in range(0, len(string_inp)): print(string_inp[value], end='')Method 3 − The ...
