通过这个解释,我们将了解当 Python 程序显示类似NameError: name '<functionName>' is not Defined的错误时会出现什么情况,即使脚本中存在该函数。 我们还了解当我们使用拼写错误的变量或未导入的内置函数时会发生什么,以及如何在 Python 中避免这些错误。 避免在 Python 中声明之前调用函数 Python 中出现NameE
What Triggers the “Function is Not Defined” Error in Python There are a few key reasons why Python raises a “function is not defined” error: Calling a Function Before Defining It Python reads code from top to bottom. So if you try to call a function before defining it, Python won’...
当我们尝试调用未声明的函数,或在声明之前调用函数,会出现 Python “NameError: function is not defined”。 要解决该错误,请确保我们没有拼错函数名并在声明后调用它。 # ⛔️ NameError: name 'do_math' is not definedprint(do_math(50,50))defdo_math(a, b):returna + b 我们试图在声明之前调用...

In this tutorial, you'll learn how and when to use the len() Python function. You'll also learn how to customize your class definitions so that objects of a user-defined class can be used as arguments in len().
Explanation:Here we have defined a function factorial, which takes an integer as an argument, and returns the factorial of the number. If you want to learn more about Python functions, please refer: Conclusion So far in this blog, we have learned how to define a function using def keyword...
