Hiring the development resources that fit the project and job requirement perfectly is difficult. Without a doubt, everyone wants to hire experienced and talented resources. However, figuring out which is which is not a piece of cake. To distinguish senior resources from juniors we have listed a few approaches through which you can figure the right python developer and thus, hire the perfect fit.
Reading files the right way
Reading a file not just successfully but doing it the right way. Along with the file the developer who can read the comprehensions and splits is a good developer. If a file contains numbers and each number is written in one line, knowledgeable python developers will loop through the numbers and represent them in one line.
Here is a sample code to help you understand the concept.
A junior developer will use python for or if-else loop just like the example above. However, an expert or senior developer will use the following approach using split() method.
This is a list comprehension method which compresses various lines of code into one. And, that is without becoming slow, in-efficient, or hard to understand. While here beginner python coders might see functions which they are not familiar with, understanding them is still not a problem.
Forget multiple if-else statements and move to “enum”
Talking about the beginner approaches, instead of using multiple if-else statements using “enum” is much better. Beginner python programmers for hire use an if-else loop which is not a bad choice but it will cause the developer problems as input/data increase.
Check this example: if the program reads certain value it gives certain number, i.e. X=1, Y=2, Z=3.
You see how the code becomes more readable and how using enum will solve so many problems.
Forget dictionaries and switch to lookup tables instead
Using Enum for something like a-z values will also become a pain, because lowercase and upper case a-z have values 1-26 and 27-52 respectively. So, if you hire a python programmer who is a beginner will definitely mess things up. A novice or mid level developer might use dictionaries but the real and experience python developer will go for a lookup table.
Using string as a lookup table has reduced code to one-line.
It can also be done using just a lookup table:
Advanced slicing
Every python coder is familiar with slicing, and loops but expert python developers know they can define step size and do slicing in the best way possible.
What junior developer would do: use nested for loop
What would a senior developer do: use slicing
Conclusion
Above mentioned tricks and insights are to distinguish junior and beginner python developers from senior and expert developers. These are only tricks that can help you find the right developer for you, and not something you should completely rely on to find developers. Analyzing different patterns how python coders at different levels work is the key to finding the perfect fit for your company.
