However, when you try to print the information of the filtered Python jobs like you’ve done before, you run into an error:Python >>> for job_card in python_jobs: ... title_element = job_card.find("h2", class_="title") ... company_element = job_card.find("h3", class_=...
any value can be passed for a given parameter, so it’s generally a good idea to make sure users know how to use your function correctly; in Python this is done by providing a documentation string (“doc-string”) string literal as the first non-commented line of code inside the fu...
In this example, you create a three-dimensional array with the shape(2, 3, 4)where each element is a random integer between1and20. You use the functionnp.random.randint()to create an array this time. The functionlen()returns2, which is the size of the first dimension. ...
