[英]Python open csv file copy to variable close file use variable?
I am trying to read a csv file, copy it, close the file and use the copy.我正在尝试读取 csv 文件,复制它,关闭文件并使用副本。 I need to move away from the with or csv.reader block.
我需要远离 with 或 csv.reader 块。 after hours of searching i found this:
经过数小时的搜索,我发现了这个:
fr = open('my_symbols.csv', 'r')
csv.reader(fr)
my_symbol_list = deepcopy(fr)
fr.close()
But that does not work either.但这也不起作用。 Anybody have any hints or suggestions?
有人有任何提示或建议吗? There must be a simple answer rigth?
必须有一个简单的答案吗?
Thanks in advance提前致谢
Skip跳过
#make variable outside of 'with'
filelines = []
with open('my_symbols.csv','r') as fr:
filelines = fr.readlines()
#after with (file is now closed), use the variable.
#you may need to split up the lines further in to columns
print(filelines[0])
