基数10のint（）の無効なリテラルはどういう意味ですか？

Question

私は映画のセンチメント分析を書いていますが、コードには1つのエラーがあります。これは、基数10のint（）の無効なリテラルです。コードはムービーレビューとスコアを含む別々のテキストファイルを読み込みます。 ex）4この映画は素晴らしかったです。助けてくれてありがとう！編集：エラーがここに表示されます：ライン38、スコア= INT（lineSplits [0] .strip（））

Answer 1

をそれは、intが0-9ない文字で何をすべきかわからないことを意味します。あなたは外の数を引くしたいいくつかの任意の文字列を持っている場合は、正規表現を使用することができ、その代わりに：

score = int(lineSplits[0].strip()) 

桁の最初のグループをつかむだろう

score = int(re.search('[0-9]+', lineSplits[0]).group())) 

ような何か。
