是否可以从 Julia 调用 Python 函数并返回其结果?

Is it possible to call a Python function from Julia and return its result?(是否可以从 Julia 调用 Python 函数并返回其结果?)

问题描述

我正在使用 Python 从网络上抓取数据.我想使用这些数据在 Julia 中运行计算.

I am using Python to scrape data from the web. I want to use that data to run calculations in Julia.

是否可以在 Julia 中调用该函数并返回其结果，或者我最好只导出到 CSV 并以这种方式加载数据?

Is it possible to call the function in Julia and return its result, or am I better off just exporting to a CSV and loading the data in that way?

推荐答案

当然.请参阅 PyCall.jl.

julia> using PyCall

julia> @pyimport bs4

julia> @pyimport requests

julia> r = requests.get("https://stackoverflow.com/questions/46638265");

julia> soup = bs4.BeautifulSoup(r.content);

julia> soup.title.string
"Is it possible to call a Python function from Julia and return its result? - Stack Overflow"

julia> soup.select_one(".answercell p").text
"Absolutely.  See PyCall.jl."
