Decoding Bytes to String in Python 3
In Python, bytes objects represent binary data, while strings hold textual information. If you've acquired a bytes object from an external source, such as the standard output of a program, you may need to convert it to a string for processing or display.
In Python 3, you can utilize the decode() method to convert a bytes object into a string:
bytes_object = b'binary data' string = bytes_object.decode("encoding")
Where "encoding" represents the encoding of the bytes object. For instance, if the data is encoded in UTF-8, you would use:
bytes_object.decode("utf-8")
Example:
Consider the following output from the ls command, captured as a bytes object:
>>> from subprocess import * >>> stdout = Popen(['ls', '-l'], stdout=PIPE).communicate()[0]
To convert this bytes object to a printable string, we can use:
stdout_string = stdout.decode("utf-8") print(stdout_string)
The above is the detailed content of How Do I Decode Bytes to a String in Python 3?. For more information, please follow other related articles on the PHP Chinese website!

In 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.

Using 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.

Key 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 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.
