在阅读本书之前,您应该了解 Python 编程的基础知识,比如基本语法,变量类型,元组数据类型,列表字典,函数,字符串和方法。在python.org/downloads/上有两个版本,3.7.2 和 2.7.15。在本书中,我们将使用版本 3.7 进行代码示例和包安装。 本章的示例和源代码可在 GitHub 存储库中找到:github.com/PacktPublishing/Mast...
Breakpoints can also be set to trigger based on expressions, hit counts, or a combination of both. The Python Debugger extension supports hit counts that are integers, in addition to integers preceded by the ==, >, >=, <, <=, and % operators. For example, you could set a breakpoint...
@app.route("/") def home(): return "Hello World! I'm using Flask." Tip You can use multiple decorators on the same function, one per line, depending on how many different routes you want to map to the same function. Save the app.py file (Ctrl+S). In the terminal, run the app...
You can combine pure functions by using the output produced by your first pure function as the parameter of the other function. # First Pure Functiondefincrease2(arr):cArr=arrforiinrange(len(cArr)):cArr[i]=cArr[i]+2returncArr# Second Pure FunctiondefgetDouble(arr):cArr=arrforiinrange(le...
In addition, you’ve learned about the importance of keeping dependencies up to date and alternatives to pip that can help you manage those dependencies. By taking a closer look at pip, you’ve explored an essential tool in your Python development workflows. With pip, you can install and man...
Previously, we used to define generics usingTypeVarsyntax.TypeVaris a feature of the Python type hinting system that allows you to create a placeholder for a type that will be specified later when a function or class is used. It is primarily used to indicate that a particular type can be ...
However, this window isn't available when using mixed-mode C/C++ debugging.To use the Debug Interactive window, select Debug > Windows > Python Debug Interactive (Shift+Alt+I).The Debug Interactive window supports special meta-commands in addition to the standard REPL commands, as described in...
To convert an integer to a float, use the float() function in Python. Similarly, if you want to convert a float to an integer, you can use the int() function. a_int = 3 b_int = 2 # Explicit type conversion from int to float c_float_sum = float(a_int + b_int) print(c_fl...
