我刚刚离开了PC(使用Python 2.7)并且有一个我刚刚完成的脚本(在下面转载)。它在工作中运行良好,我只是想添加一两件事。但我回到家并使用我的Mac版Python(3.2.2),我收到以下错误:
Traceback (most recent call last):
File "/Users/Downloads/sda/alias.py", line 25, in <module>
for row_2 in in_csv:
File "/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/encodings/ascii.py", line 26, in decode
return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 304: ordinal not in range(128)
我的代码在这里:
import csv
inname = "Fund_Aliases.csv"
outname = "output.csv"
def first_word(value):
return value.split(" ", 1)[0]
with open(inname, "r") as infile:
with open(outname, "w") as out file:
in_csv = csv.reader(infile)
out_csv = csv.writer(outfile)
column_names = next(in_csv)
out_csv.writerow(column_names)
id_index = column_names.index("id")
name_index = column_names.index("name")
try:
row_1 = next(in_csv)
written_row = False
for row_2 in in_csv:
if first_word(row_1[name_index]) == first_word(row_2[name_index]) and row_1[id_index] != row_2[id_index]:
if not written_row:
out_csv.writerow(row_1)
out_csv.writerow(row_2)
written_row = True
else:
written_row = False
row_1 = row_2
except StopIteration:
# No data rows!
pass
答案 0 :(得分:5)
看起来Fund_Aliases.csv
不是ascii文件。
根据Python3 docs:
由于open()用于打开CSV文件进行读取,因此该文件将由 默认使用系统默认编码解码为unicode(请参阅 是locale.getpreferredencoding())。使用不同的文件解码文件 编码,使用open的编码参数:
with open('some.csv', newline='', encoding='utf-8') as f:
reader = csv.reader(f)
因此请尝试指定encoding
参数。
