For data manipulation in python we may come across situation to convert a dictionary object into a string object. This can be achieved in the following ways.with str()In this straight forward method we simple apply the str() by passing the dictionary object as a parameter. We can check the type of the objects using the type() before and after conversion.Example Live DemoDictA = {"Mon": "2 pm", "Wed": "9 am", "Fri": "11 am"} print("Given dictionary : ", DictA) print("Type : ", type(DictA)) # using str res = str(DictA) # Print result print("Result as string:", res) print("Type of Result: ", type(res))OutputRunning the above ...

As part of data manipulation, we will come across the need to have a single case for all the letters in a string. In this article we will see how to take a list which has string elements with mixed cases. We then apply some python functions to convert them all to a single case.With lower()The lower function is a string function that can convert the entire string to lower case. So we use lambda and map to apply the lower function to each of the elements in the list.Example Live DemolistA = ['MoN', 'TuE', 'FRI'] # Given list print("Given list ... Read More

The byte string in python is a string presentd with letter b prefixed on it. In this article we will see how to convert a dictionary with the bytecode string into a normal dictionary which represents only strings.With decode and asciiPython string method decode() decodes the string using the codec registered for encoding. It defaults to the default string encoding. We use it to convert the bytecode value into normal asci values by supplying ascii as the parameter to the decode function.Example Live Demobstring = {b'day': b'Tue', b'time': b'2 pm', b'subject': b'Graphs'} print(bstring) # Use decode stringA = {y.decode('ascii'): bstring.get(y).decode('ascii') for ...

As python handles various data types, we will come across a situation where a list will appear in form of a string. In this article we will see how to convert a string into a list.With strip and splitWe first apply the strip method to remove the square brackets and then apply the split function. The split function with a comma as its parameter create the list from the string.Example Live DemostringA = "[Mon, 2, Tue, 5, ]" # Given string print("Given string", stringA) print(type(stringA)) # String to list res = stringA.strip('][').split(', ') # Result and its type print("final list", res) ...

A nested list is a list whose elements are lists themselves. If we have a python data container which is a nested list, we may sometimes need to convert it into a flattened list so that each element can be processed further.Even the inner elements can also be nested themselves. And there can be many layers of nesting. So we will approach this problem with recursion. We will keep checking if the element is nested and then keep going applying the function again and again until the element is no longer a list. Once it is found that element is ... Read More

Sometimes we may have a list whose elements are integers. There may be a need to combine all these elements and create a single integer out of it. In this article we will explore the ways to do that.With joinThe join method can Join all items in a tuple into a string. So we will use it to join each element of the list by iterating through them through a for loop.Example Live DemolistA = [22, 11, 34] # Given list print("Given list A: ", listA) # Use res = int("".join([str(i) for i in listA])) # Result print("The integer is : ...

Converting one data container into another in python is a frequent requirement. In this article we will take a list and convert into a tuple where each element of the tuple is also a list.With tupleWe can apply the tuple function straight to the list. But we have to also put a for loop in place so that each element is enclosed in a [].Example Live DemolistA = ["Mon", 2, "Tue", 3] # Given list print("Given list A: ", listA) # Use zip res = tuple([i] for i in listA) # Result print("The tuple is : ", res)OutputRunning the above code ...

During data analysis using python, we may come across a need to pair-up the consecutive elements of a list. In this article we will see the various ways to achieve this.With index and rangeWe will design an expression to put the consecutive indexes of the list elements together. And then apply the range function to determine the maximum number of times this pairing of consecutive elements will go on.Example Live DemolistA = [51, 23, 11, 45] # Given list print("Given list A: ", listA) # Use res = [[listA[i], listA[i + 1]]    for i in range(len(listA) - 1)] # Result ...

Python has great libraries to manipulate data. We may come across a need to find the maximum product of two consecutive numbers which are part of the big string. In this article we will see the ways to achieve that.With zip and maxWe convert the string into a list. Then create pairs from the consecutive elements with help of slicing. Applying * we multiply the pair and then take the max value from the result of the multiplication from each of the pairs.Example Live DemoAstring = '5238521' # Given string print("Given String : ", Astring) # Convert to list Astring = ...

Pyhton has great data manipulation features. In this article we will see how to combine the elements from two lists in the same order as they are present in the lists.With zipThe zip function can take in the two lists as parameters and concatenate them. We design a for loop to capture these combinations and put them into a new list.Example Live DemolistA = ["Outer-", "Frost-", "Sun-"] listB = ['Space', 'bite', 'rise'] # Given lists print("Given list A: ", listA) print("Given list B: ", listB) # Use zip res = [i + j for i, j in zip(listA, listB)] # Result ...
