The gap between corporate expectations and reality for Python programming skills

The gap between enterprise expectations and reality for Python programming skills

Abstract: Python, as a popular programming language, is increasingly used in enterprises. Enterprises' demand for Python programming skills is also increasing, but there is a certain gap between the actual work of many employees and the enterprises' expectations for Python programming skills. This article explores the gap between corporate expectations and reality for Python programming skills from three aspects: the foundation of programming skills, practical experience, and problem-solving abilities, and provides corresponding code examples.

1. The basis of programming skills

The company’s expectation for Python programming skills is that employees can master basic knowledge of Python’s basic syntax, data types, variables, conditional statements, loop statements, etc., and be able to Use them flexibly to solve real problems.

However, the reality is that many employees only stay in the learning of basic knowledge in the process of learning Python, and have little understanding of complex data structures and algorithms. A simple example is provided below to illustrate this issue.

Code example 1:

# 计算斐波那契数列的第n个数
def fibonacci(n):
    if n <= 1:
        return n
    else:
        return fibonacci(n-1) + fibonacci(n-2)

n = int(input("请输入斐波那契数列的项数："))
result = fibonacci(n)
print("斐波那契数列的第", n, "项是：", result)

The above code uses recursion to calculate the nth number of the Fibonacci sequence. However, the recursive algorithm becomes very slow and inefficient when calculating numbers greater than 30. If an employee can only use recursive algorithms to solve this problem, it will obviously not be able to meet the needs of the enterprise.

2. Lack of practical experience

The company’s expectation for Python programming skills is that employees can continuously improve their programming skills in practice and master commonly used data analysis, machine learning, Programming skills in web crawlers and other fields, and be able to independently solve practical problems.

However, the reality is that many employees lack experience in practice and only stay in the classroom. A simple example is provided below to illustrate this issue.

Code Example 2:

import requests

url = "https://api.github.com/users/octocat/repos"
response = requests.get(url)
repos = response.json()

for repo in repos:
    print(repo["name"])

The above code uses the requests library to obtain all repositories of the octocat user on GitHub and prints the name of the repository. If an employee only uses the requests library according to the examples in the tutorial, he will encounter difficulties in processing other requests.

3. Insufficient problem-solving ability

Enterprises’ expectations for Python programming skills are that employees can have good problem-solving skills, be able to independently analyze and solve problems encountered, and be able to follow good programming standards and coding styles.

However, the reality is that many employees will choose to turn to others for help when they encounter difficulties in solving problems, lacking the ability to solve problems independently. A simple example is provided below to illustrate this issue.

Code example three:

def divide_numbers(a, b):
    try:
        result = a / b
        return result
    except ZeroDivisionError:
        return "除数不能为零"

a = int(input("请输入被除数："))
b = int(input("请输入除数："))
result = divide_numbers(a, b)
print("商为：", result)

The above code defines a function to calculate the quotient of two numbers. When the divisor is zero, a ZeroDivisionError exception will be thrown and "the divisor cannot be zero" will be returned. . However, if an employee encounters a division by zero situation when using it, he cannot solve the problem independently and can only seek help from others.

Conclusion:

There is a certain gap between corporate expectations for Python programming skills and reality. The key to solving this problem is to strengthen the learning of basic knowledge while focusing on the accumulation of practical experience and improve problem-solving capabilities. Employees can continuously improve their Python programming skills by participating in training courses, participating in project development and code reviews, etc., thereby meeting the company's demand for Python programming skills.
