Whether you’re a data scientist or a programmer handling large quantities of data, you’ll soon overcome pandas’s learning curve and start solving complex problems in less time.
Many people use NumPy — but “pandas” extends NumPy, providing additional functionality that makes it easy, and even fun, to do data analysis. You can think of “pandas” as an automatic transmission, compared with NumPy’s manual transmission. Both work, but “pandas” makes it easier, and allows us to think at a higher level of abstraction. The thing is, “pandas” uses data structures that look and act different from regular Python data structures. And many of the classic techniques for working with Python are a bad idea with “pandas”. So learning what you should (and shouldn’t) do with “pandas” can take some time, even if you’re an old hand with Python.
