What is Python?
Python is a high-level programming language with elegant and concise syntax. It was created by Dutch programmer Guido van Rossum and released in the early 1990s. Python's design philosophy emphasizes readability and clarity, making code writing easy and understandable. This language marks code blocks with its unique indentation method, and abandons the traditional curly braces, so that the code style is more uniform, and it also promotes standardized writing habits.
For example, the following is a simple Python code snippet:
def greet(name):
print("Hello, " + name + "!")
greet("Alice")
