意外的縮進錯誤

對於python /編程來說很新奇，一直在編寫腳本，但在的第for line in csv.reader(open(filename), delimiter="\t"):附近遇到了縮進錯誤，但可以使用一些幫助將它整理出來，有什麼想法？意外的縮進錯誤

你能否解釋一下你有什麼反應，幫助學習過程謝謝！

Python中不需要圍繞'if'條件的括號。 – filmor

使用pylint來檢測語法錯誤，就像這樣。 E：92，0：意外縮進（語法錯誤） –

如果你看到一個非常奇怪的編譯器錯誤，它看起來不能從它表示它的行中看到前一行。適用於此，也適用於其他語言中缺少分號，括號等。 – RemcoGerlich

你報的應該是一個縮進更

sample_names.append（sample_name）

此行的一個前行我的意思是:)

謝謝幫助很多！ – user3234810

縮進錯誤。

嘗試縮進

sample_names.append(sample_name)
