我有一个csv文件(名为“test.csv”),其中包含带有元组的列表:
[('calculation', 1468171987.4406562, None), ('calculation', 1468171988.5840397, None), ('calculation', 1468171989.8159678, 1.9041595458984375)]5)]
如何导入此csv文件并将其内容保存到以下列表中:
record = []
导入后
record = [('calculation', 1468171987.4406562, None), ('calculation', 1468171988.5840397, None), ('calculation', 1468171989.8159678, 1.9041595458984375)]
这就是我的尝试:
import csv
with open ("test.csv", 'rb') as f:
reader = csv.reader(f)
record = reader
尝试2:
import csv
with open ("test.csv", 'rb') as f:
reader = csv.reader(f)
record = list(reader)
然后我收到此错误:
_csv.Error: iterator should return strings, not bytes (did you open the file in text mode?)
答案 0 :(得分:0)
现在您已经拥有了一个CSV阅读器(我假设您的实际代码正确缩进并且运行时没有语法错误),您需要使用它来输入文件中的行。最简单的方法是:
record = list(reader)
答案 1 :(得分:0)
您可以使用ast.literal_eval
import ast
with open ("test.csv", 'r') as f:
for line in f:
list = ast.literal_eval(line)
print list
