試圖將 csv 讀入列表。代碼如下：import csvwith open('file.csv','r') as fin: reader = csv.reader(fin) mylist = list(reader)print (mylist)def gen_list(): with open('file.csv','r') as fin: reader = csv.reader(fin) mylist = list(reader) print (mylist)def main(): gen_list() return 0我的輸出是：[['one','two','three']]Traceback():....line 11, in gen_listreader = csv.reader(fin)AttributeError: 'str' object has no attribute 'reader'我可以通過將“import csv”作為 gen_list 函數(shù)的第一行來防止發(fā)生此錯(cuò)誤。為什么代碼在放在函數(shù)中時(shí)不起作用？

原來我偶然在另一個(gè)函數(shù)中使用了 csv。一旦我更改了 csv，問題就消失了
功能：
def get_list(csv):
with open(csv,'rt') as fin:
for line in fin:
drList.append(gen_list(line))
return (drList)

試試這個(gè)：
import csv
with open('file.csv','r') as fin:
reader = csv.reader(fin)
mylist = list(reader)
print (mylist)
def gen_list():
with open('file.csv','r') as fin:
reader = csv.reader(fin)
mylist = list(reader)
print (mylist)
def main():
gen_list()
return 0
看來，縮進(jìn)reader的內(nèi)open內(nèi)gen_list是錯(cuò)誤的
