Python is one very special language. No matter how well you know this language, an everyday new feature of this is seeing the daylight. It is one of the most popular and demanding programming languages. This is because of many reasons such as-

  • It is easy to learn.
  • It has a huge range of libraries.
  • It is versatile.
  • It is readable and expressive. 

Learning Python is an integral part of a student. So, to guide the students about how to complete their assignment work easily, the Python assignment help experts associated with the Instant Assignment Help have picked the most popular tricks which will help them complete their task on time. 

So, here is a list of 8 tricks to help students complete their assignment work with ease. 

Simplify If Statement

An If statement consists of a Boolean expression followed by one or more statements. Using If statement with multiple values or to differentiate the values will be lengthy. 

if m==1 or m==3 or m==5 or m==7:

Instead of using this, you can use

if m in [1,3,5,7]:

We can also use {1, 3,5,7}; instead of [1,3,5,7]: with ‘in’ operator because ‘set’ can access each element by O(1).

Combine Multiple Strings

To concatenate multiple strings means adding one string to the end of the another in the list. For example, you could combine the string Python with the other half of the string. Since you are adding strings to one another, you can also use the + operator. 

If you want to concatenate two or more strings, you can write as:

 test = ['I', 'Like', 'Python', 'automation']

 print ' ' . join(test)

Reduce Memory Heads Using _Slots_


Have you ever observed why Python uses a lot of resources, especially memory? To solve this problem, one of the solutions is using _slots_ to reduce the memory overhead to some extent. 

Example- import sysclass FileSystem(object):

def __init__(self, files, folders, devices):

        self.files = files

        self.folders = folders

        self.devices = devices

print(sys.getsizeof( FileSystem ))  (in this _slots_ are not used)


The output for this is- 1016


In the code below, you can see that _slots_ are used.

class FileSystem1(object):

__slots__ = ['files', 'folders', 'devices']

def __init__(self, files, folders, devices):

        self.files = files

        self.folders = folders

        self.devices = devices

print(sys.getsizeof( FileSystem1 ))

The result you get for this code is: 888

Clearly, you can see the results that there are memory usage savings. 

Implement a True Switch Case Statement

Python does not have a simple switch case construct. Coming from a Java or C++ background, you may find this to be a bit odd. In python, it is different. You do not have the same way to write the switch statement. You can use Python’s built- in dictionary to implement the case statement. 

To implement switch case, you can use this example: 

>>> def week(i):

switcher={

0:'Sunday',

1:'Monday',

2:'Tuesday',

3:'Wednesday',

4:'Thursday',

5:'Friday',

6:'Saturday'

}

return switcher.get(i,"Invalid day of week")


Calculate the Factorial of Any Number in One Line

Factorial of a number is the multiplication of all numbers smaller than or equal to the given number. 

Example: factorial of 5 is:

5*4*3*2*1= 120

In Python, we find the factorial of a number using the ternary operator. It is commonly known as the conditional operator. So, to calculate the factorial of the given number, let’s look at the code given below:

def factorial(n):

  return 1 if (n == 1 or n == 0) else n * factorial(n - 1); 

 num = 5; 

print("Factorial of", num, "is", factorial(num)); 

In the above code, only a single line code is needed to find the factorial. 

Output: Factorial of 5 is 120


Find the Most Frequent Value in the List


Let’s take an example- Input : [3, 1, 3, 2, 1, 3]

Output : 3

In the above example, we can see that 3 is the most frequent value in the list. So in your assignment, if you get this type of question, need not worry as the experts have a solution for this also. There are 5 best approaches to do this:

1.Naive Approach

2.Pythonic Naive Approach

3.Using Counter

4.By Finding Mode

5.Using Python Dictionary

You can choose the best approach that suits you to solve this type of question when they come in your academic paper. 

Form a Unified List Without Using Any Loops

If you have a list with nested lists or tuples in an element, then you can use the below given code as a reference to solve the problem. 

def unifylist(l_input, l_target):

            for it in l_input:

            if isinstance(it, list):

            unifylist(it, l_target)

            elif isinstance(it, tuple):

            unifylist(list(it), l_target)

            else:

    l_target.append(it)

       return l_target


test =  [[-1, -2], [1,2,3, [4,(5,[6,7])]], (30, 40), [25, 35]]

print(unifylist(test,[]))


So, for the above code the result will be: 

[-1, -2, 1, 2, 3, 4, 5, 6, 7, 30, 40, 25, 35]

These were some of the tricks that will surely help you in writing the best Python assignment. However, if you are reading this and there isn't much time left to draft an assignment then you can reach out to the best online assignment help providers for getting your job done.
