Python for Web Development

 

Python is known for being simpler to learn than languages like C, C++, Java, etc. Python languages have a syntax that resembles that of English words. Learning Python is enjoyable, then. In the big picture, you are aware that we write hundreds of lines of code when creating applications or writing software. Note that Python commands and syntax are simple to comprehend for English speakers or learners. Would it not be easier for you to detect errors in a source file written in python than in source code written in another language? 

Python-based frameworks are widely used for web development. Python-based Django is a potent framework for creating numerous apps and developing websites. Due of its large community, Django comes highly recommended. Let's go on to the main content without further ado.

It doesn't matter which Python frameworks you use for it. You are aware that to create your own applications, you must write code in Python within those frameworks. Therefore, having a solid understanding of the Python language is necessary. We'll now talk about some examples of programs that could be used to create a website or an application.

Sorting words alphabetically for proper indexing

Python Code:

S = input("Submit the whole paragraph: ") def Func(S): #splits the entire paragraph's words into separate words with whitespace between them. Words = S.split(" ") for i in range(len(Words)): # convert all the words into lowercase Words[i]=Words[i].lower() S = sorted(Words) print(' '.join(S)) # function call Func(S)

Output

Submit whole paragraph: Egg Fruit Elderberry Feijoa Fig Breadfruit Monstera deliciosa Mulberry Nance Nectarine Loganberry Longan Loquat Avocado Banana Bilberry Peach Pear Persimmon Plantain Coconut Crab apple Cranberry Currant Damson Apple Apricot

Result

apple apple apricot avocado banana bilberry breadfruit coconut crab cranberry currant damson deliciosa egg elderberry feijoa fig fruit loganberry longan loquat monstera mulberry nance nectarine peach pear persimmon plantain

Prefix and suffix addition in web applications using Python

prefix_str = input("what prefix you want to add: ") suffix_str = input("what suffix you want to add: ") # initializing list test_list1 = input("Submit the whole paragraph: ") test_list = test_list1.split(" ") #test_list = ['a', 'b', 'c', 'd'] # printing list print("The original list : " + str(test_list)) # Append suffix / prefix to strings in list result = ([prefix_str + sub + suffix_str for sub in test_list]) # Printing result print(result)

Output

any prefix you want to use: <a href="#">     

any suffix you want to use: </a>

Submit the whole paragraph: Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware Florida Georgia

The original list : ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California', 'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia']

Result

['<a href="#">Alabama</a>', '<a href="#">Alaska</a>', '<a href="#">Arizona</a>', '<a href="#">Arkansas</a>', '<a href="#">California</a>', '<a href="#">Colorado</a>', '<a href="#">Connecticut</a>', '<a href="#">Delaware</a>', '<a href="#">Florida</a>', '<a href="#">Georgia</a>']

...Program finished with exit code 0

Press ENTER to exit console.: <a href="#">     

Printing the above result as a text (.txt) file and alphabetizing

# Python3 code to demonstrate working of # Append suffix / prefix to strings in list # initializing list myparagraph = input("Submit whole paragraph: ") test_list = myparagraph.split(" ") # initializing prefix & suffix prefix = input("prefix: ") suffix_str = input("suffix: ") # printing list print("The original list : " + str(test_list)) # Append suffix / prefix to strings in list result = ([prefix + sub + suffix_str for sub in test_list]) result.sort(); # Printing result print(result) with open('output.txt', 'w') as txt_file: #looping over the each ist element for element in result: #writing to file line by line txt_file.write('%s\n' % element)

Output

Submit whole paragraph: California Colorado Delaware Florida Georgia Alabama Alaska Arizona Arkansas  Connecticut 

prefix: <a href="#">

suffix: </a>

The original list : ['California', 'Colorado', 'Delaware', 'Florida', 'Georgia', 'Alabama', 'Alaska', 'Arizona', 'Arkansas', '', 'Connecticut', '']

Result

['<a href="#"></a>', '<a href="#"></a>', '<a href="#">Alabama</a>', '<a href="#">Alaska</a>', '<a href="#">Arizona</a>', '<a href="#">Arkansas</a>', '<a href="#">California</a>', '<a href="#">Colorado</a>', '<a href="#">Connecticut</a>', '<a href="#">Delaware</a>', '<a href="#">Florida</a>', '<a href="#">Georgia</a>']
