pandas dataFrame to_excel 报错[ UnicodeDecodeError: 'ascii' codec can't decode byte 0xe7 in position 7

问题提出

python code

import pandas as pd
df = pd.read_csv("text.csv", sep="\t")
df.to_excel("test.xlsx")

error info

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe7 in position 7: ordinal not in range(128)

解决办法

import sys
sys.setdefaultencoding('utf-8')
import pandas as pd
def csv2excel(fp):
df = pd.read_csv(fp, sep="\t")
cols = df.columns
## 转换每一列的编码
for e in cols:
df[e] = df[e].map(lambda x: str(x).decode("utf8").encode("raw_unicode_escape").decode("raw_unicode_escape"))
# 这里的 utf8 为 python 运行环境默认编码, 即 sys.getdefaultencoding()
print e
df.to_excel(fp.replace(".csv", ".xlsx"))
print fp

if __name__ == "__main__":
fp = "test.csv"
csv2excel(fp)
