ValueError：以10為底的int（）的無效文字：''在python中導入請求模塊時出錯

Question

我在交互外殼程序中導入請求模塊時使用Ubuntu 18.04 OS，但注意到以下錯誤：不知道為什么我使用如下pip3安裝請求安裝了pip3請求，當我嘗試使用pip3卸載請求卸載請求時，效果很好，並且即使在安裝時也顯示已成功安裝了版本號

Answer 1

您將自己的模塊命名為random.py ，它掩蓋了內置的random模塊 。 額外的錯誤是由錯誤處理掛鈎本身具有錯誤引起的，但最終是由它們期望內置模塊並獲取不相關的模塊引起的。 不要為內置模塊命名。

似乎還有一個錯誤，您自己的random.py嘗試執行int(input())並失敗了，因為它沒有從stdin讀取任何內容，但這是一個相當明顯的錯誤（您未輸入任何內容，或者您​​以這種方式啟動了它一種關閉stdin的方式）。
