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 pddf = 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

直接上 code

import syssys.setdefaultencoding('utf-8')import pandas as pddef 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 fpif __name__ == "__main__":    fp = "test.csv"    csv2excel(fp)
