Everyone knows that Python can be used to do data calculations, so how to express exponentiation in Python?
Look at the following example:
To calculate the results of 4 * 4 and 5 * 5, you can write like this
As you can see, the output results are 16 and 25 respectively. If we want to calculate the multiplication of 4*4*4*4, or the multiplication of 2*2*2*2*2*2*2, it is very cumbersome to use the above method. How can we achieve it?
Here we can use exponentiation!
In Python, ** is used to represent exponentiation (there is no space between the two asterisks). With exponentiation, no matter how many identical numbers are multiplied, it can be easily done. solved!
Look at the following example
What is the result of calculating 4*4*4*4
As you can see, Python directly The result of 4 raised to the 4th power is given, and the result is 256
Look at another example: Calculate the 30th power of 2
Similarly, Python gives accurate results! Compared with the first example, using exponentiation greatly improves calculation efficiency, saves time, and the code is simpler and clearer!
The above is the detailed content of How to express power in Python. For more information, please follow other related articles on the PHP Chinese website!

How to concatenate two lists in python 3?May 14, 2025 am 12:09 AMIn Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.
Python concatenate list stringsMay 14, 2025 am 12:08 AMUsing the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Python: what are the key featuresMay 14, 2025 am 12:02 AMKey features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.
Python: compiler or Interpreter?May 13, 2025 am 12:10 AMPython is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
