如何使用python用新行将列表保存为.csv文件？

Question

我想在.csv文件中保存python列表,例如我有一个这样的列表:

['hello','how','are','you']

我想像这样保存它:

colummn,
hello,
how,
are,
you,

我尝试了以下方法:

myfile = open('/Users/user/Projects/list.csv', 'wb')
wr = csv.writer(myfile, quoting=csv.QUOTE_ALL,'\n')
wr.writerow(pos_score)

Answer 1

使用pandas to_csv(http://pandas.pydata.org/pandas-docs/dev/generated/pandas.DataFrame.to_csv.html)

>>> import pandas as pd
>>> df = pd.DataFrame(some_list, columns=["colummn"])
>>> df.to_csv('list.csv', index=False)

Answer 2

如果您想要不同行上的所有单词,您需要将deliiter设置为\n:

l = ['hello','how','are','you']
import  csv

with open("out.csv","w") as f:
    wr = csv.writer(f,delimiter="\n")
    wr.writerow(l)

输出:

hello
how
are
you

如果你想要一个尾随逗号:

with open("out.csv","w") as f:
    wr = csv.writer(f,delimiter="\n")
    for ele in l:
        wr.writerow([ele+","])

输出:

hello,
how,
are,
you,

我建议只编写没有尾随逗号的元素,使用尾随逗号没有任何好处,但以后可能会导致问题.
