Definition of Python Competitive Programming
Python competitive programming sponsors for the ACM ICPC, a prominent competition, sparked interest in competitive programming. This resulted in more individuals returning to the fundamentals and learning the algorithms that serve as the foundation for more complex packages that are used to construct high-level packages. Unfortunately, there isn’t much information available on how to use data structures or even the scoping restrictions of Python.
Why Python Competitive Programming?
Python is one of those programming languages that makes things simple and easy. Anyone who has experimented with Python for Competitive Coding develops a mild addiction to its numerous features. For the majority of intense programming competitions, Python popular language among programmers. Using Python, the majority of the issues can be resolved quickly and simply.
Writing Python code quickly enough to solve some complex problems is frequently difficult. Most programmers now favor Python above all other languages. Python’s simplicity and short learning curve are the key reasons behind this. In a week, we can develop solid Python programming skills. Although it is simple to grasp, we have problems with the Python program’s sluggishness and code run time when we participate in competitive programming.
Key Takeaways
- Python provides a fantastic opportunity to demonstrate our coding abilities during examinations and competitions, whether we are a novice or seasoned professionals.
- It makes it easier for us to understand data structure ideas, solve challenging programming issues, and write error- and bug-free solutions quickly.
Why Choose Coding Python in Competitive Programming?
There are multiple reasons to choose python in competitive programming. The below point shows why we choose python in competitive programming as follows:
- Easy to use – Python contains simple syntax and it’s very easy to use. Python is easy to learn for new developers.
- Versatile – Python is used in multiple languages, so it is called versatile. We use python in web, data analysis, and scientific computing.
- Large community – Python has an active and large community of developers who constantly contribute to the language also we can develop new tools and libraries.
- Standard and large libraries – Python comes with standard and large libraries that provide useful tools and tasks such as regular expressions or file I/O.
- Dynamic typing – Python uses dynamic typing that allows prototyping and development that was faster, and it is not required to declare variable type.
- Readable code – Python code is readable as compared with other languages. It is described as an executable pseudo-code because it is easy to understand.
- Interoperability – We can integrate python with any other programming language. It will make an excellent choice for the project which involves many languages.
- Popular in data science – Python is a more popular language in ML and data science, because of its versatility and libraries such as pandas, numpy, and many more.
Python in Competitive Programming Coding
The below point shows why we use python as a competitive programming language as follows. We use the generator and other points of python.
1. Use of generator
The generator in python is used to reduce the space and time complexities better than other function that was used in python. The below example shows the use of generators as follows.
Code:
def FG():
yield 1
yield 2
yield 3
for i in FG():
print(i, end=" ")Output:
2. Use of built-in libraries and functions
To use built-in functions and libraries is better to use the normal approach. The below example shows how we can use built-in functions and libraries in python as follows.
Code:
import time
st = time.time ()
def get_square (x):
return x**2
l1 = [i for i in range(100)]
l2 = list(map(get_square,l1))
print(len(l2))
print("Code time: %s seconds."% (time.time() - st))Output:
3. Use itertools
The module of itertools helps us to solve complex problems. Below example shows to find all permutations listed as follows.
Code:
import itertools
iter = list(itertools.permutations ([11, 15, 19]))
print(iter)Output:
4. Use of map functions
When we required input of all elements of an integer array in one line and the same is separated with space then we can use the map function. The below example shows how we can use the map function as follows.
Code:
m = list(map(int,input("Enter ele: ").split()))
print(m)Output:
5. Concatenation of string
To concatenate strings we can use two approaches first is the string to string and the other is the join function. To use the join function, we need to concatenate the process in a single line. The below example shows string concatenation using the join as follows.
Code:
import time
ST = time.time()
l = [str(i) for i in range(100)]
st1 = ""
st1.join(l)
print(len(st1))
print("Time: %s seconds."% (time.time() - ST))Output:
Importance of Python in Competitive Programming
Python is the most popular language in day-to-day life. Python contains operations in multiple operations like web development, AI, ML, and data science.
Below is the importance of python in competitive programming as follows:
- Ease and speed of use in unison – Competitive code is used to find the best solution of python language. At the time we save coding, it will utilize to solve the problem. For new developers, python is easy to understand.
- Data structure range – There are multiple data structures available in the programming language of python. Those data structures are useful for developers who work in competitive programming.
- Data type declaration – Work with python we do not need to declare any variable and data types. It will add flexibility until it will stay required hardware limits. So, we can say that it will handle type conversions.
- Python libraries – Python hallmarks contain libraries that feature the functions of max, min, and many more.
- Combos of linked lists and arrays – The code of python comes with a unique functionality that deletes specific elements. We can perform the insertions at any of the locations.
- Unique list operations – To deal with the list size, the last accessed into the index position of -1. We do not need to specify, and it will also operate into the allocation of a dynamic array.
Advantages
Below are the advantages of python in competitive programming. It will offer multiple advantages as follows.
- Independence of variable – In python, we do not need to declare data types before using it. It will give us the flexibility to use the variable in our code.
- Common functions – The min and max functions are used to find the list of elements from the list. The function of sort allows us to sort the count function.
- Python combines aspects of linked lists and arrays – List in python provides unique functionality to delete the specified elements. This feature will render the linked list concepts.
- Unique list operations – If we are not sure about list size then we need to use index position to access the last element. So, we can backtrack the list of the element.
- Functions with a flexible number of arguments – We can pass the function arguments whose size varies every time and then we need to call the function.
Conclusion
Python is one of those programming languages that makes things simple and easy. Anyone who has experimented with Python for Competitive Coding develops a mild addiction to its numerous features. Writing Python code quickly enough to solve some complex problems is frequently difficult. Most programmers now favor Python above all other languages.
