In this scenario, we are calling a function from another file. Let us take a compute.py file having a function interest to compute the simple interest of given principal and duration. We will then write a demo.py file that has saving function, which when called makes call to interest func...

批评Python的讨论经常谈论使用Python进行多线程工作有多么困难,将矛头指向所谓的全局解释器锁(正式称为GIL),该锁阻止了多个Python代码线程同时运行。因此,如果您不是Python开发人员,并且来自其他语言(例如C ++或Java),则Python多线程模块的行为可能与您期望的不太一样。必须明确的是,只要考虑到某些因素,仍然可以用Python...
The function handler name defined at the time that you create a Lambda function is derived from: The name of the file in which the Lambda handler function is located. The name of the Python handler function. In the example above, if the file is named lambda_function.py, the handler would...
