問題の説明

plumbum: stdin に変数を送信する方法は? (plumbum: How to send a variable to stdin?)

私は現在:

(local['echo'][var] | sth)()

これは洗練されておらず、非効率的です。

リファレンスソリューション

方法 1:

I found the solution in the plumbum documentation:

You can use the shift‑left operator <<.

from plumbum import local

if __name__ == '__main__':
    var = "some text in a python variable"

    sth = local["cat"]

    x = (local['echo'][var] | sth)()
    print(x)

    print("alternative:")
    x = (sth << var)()
    print(x)
