In interactive mode, the last printed expression is assigned to the variable _. This means that when you are using Python as a desk calculator, it is somewhat easier to continue calculations, for example: >>> tax = 12.5 / 100 >>> price = 100.50 >>> price * tax 12.5625 >>> price +...
To enter interactive mode, you can open a terminal or command prompt and type “python” to start the Python interpreter. 4. Running functions and modules: In Python, you can define functions and modules, which encapsulate blocks of reusable code. To run a function, you need to call it ...
第一行是一个赋值语句,将某个值赋给了n。第二行是一个打印语句,在屏幕上显示n的值。 当你输入一个语句后,解释器会执行(execute)这个语句,即按照语句的指令完成操作。一般来说,语句是没有值的。 4.脚本模式 到目前为止,我们都是在交互模式(interactive mode)下运行Python,即直接与解释器进行交互。交互模式对学...
Matplotlib is aPythonplotting library that produces publication-quality figures. Matplotlib是一个Python绘图库,用于生成出版物质量的图形。 It can be used both in Python scripts and when using Python’s interactive mode. 它既可以在Python脚本中使用,也可以在使用Python的交互模式时使用。 Matplotlib is a v...

To test your functions, you can run your code in interactive mode. You do this with the -i flag. For example, if your code is in a file named greeters.py, then you run python -i greeters.py:Python >>> greet_bob(say_hello) 'Hello Bob' >>> greet_bob(be_awesome) 'Yo Bob,...
The mode argument specifies what kind of code must be compiled; it can be 'exec' if source consists of a sequence of statements, 'eval' if it consists of a single expression, or 'single' if it consists of a single interactive statement (in the latter case, expression statements that eval...
