Python: Detailed explanation of input() and raw_input()
Experiment
a = input('请输入:') print a
If you enter a string, an error will be reported immediately:
请输入:str Traceback (most recent call last): File "<stdin>", line 1, in <module> File "<string>", line 1, in <module>
But if you enter an integer, no error will be reported:
请输入:1010
If input
is changed to raw_input
, the keyboard input string can be recorded normally:
a = raw_input('请输入:')print a
请输入:str str
The reason
The reason is that, input
can only accept integer input:
a = input('请输入:')print type(a)
请输入:10<type 'int'>
and raw_input
can accept string input:
a = raw_input('请输入:')print type(a)
请输入:str <type 'str'>

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.
