python - 将带有俄语字符的 numpy.ndarray 写入文件

Question

我试着写numpy.ndarray归档。
我用

unique1 = np.unique(df['search_term'])
unique1 = unique1.tolist()

下一次尝试
1)

edf = pd.DataFrame()
edf['term'] = unique1
writer = pd.ExcelWriter(r'term.xlsx', engine='xlsxwriter')
edf.to_excel(writer)
writer.close()

和 2)

thefile = codecs.open('domain.txt', 'w', encoding='utf-8')
for item in unique:
    thefile.write("%s\n" % item)

但全部返回 UnicodeDecodeError: 'utf8' codec can't decode byte 0xd7 in position 9: invalid continuation byte

Answer 1

如果您将字符串编码为 utf8，则第二个示例应该可以工作。

以下在 Python2 中使用 utf8 编码文件工作:

# _*_ coding: utf-8

import pandas as pd

edf = pd.DataFrame()
edf['term'] = ['foo', 'bar', u'русском']

writer = pd.ExcelWriter(r'term.xlsx', engine='xlsxwriter')
edf.to_excel(writer)

writer.save()

输出:
