小練習 通過csv模組讀取csv檔案

主要是講我寫**的時候，出現的幾處小錯誤

import csv

def csv_read():
with open("student.csv") as f:
readers = csv.reader(f)
header = next(readers)
print(header)
for list in readers:
print(list)
if __name__ == '__main__':
csv_read()

traceback (most recent call last):

file "e:/python/try_02/try_csv.py", line 14, in csv_read()
file "e:/python/try_02/try_csv.py", line 7, in csv_read
header = next(readers)
unicodedecodeerror: 'gbk' codec can't decode byte 0xbf in position 2: illegal multibyte sequence

import csv

def csv_read():
with open("student.csv", encoding = "utf-8") as f:
readers = csv.reader(f)
header = next(readers)
print(header)
for list in readers:
print(list)
if __name__ == '__main__':
csv_read()

['\ufeff"sno"', 'sname', 's***', 'sdept', 'sage']

['08001', '張力', '男', '軟體', '18']
['08002', '張麗', '女', '**', '20']
['08003 ', '李梅', '女 ', '藝設', '19']

'\ufeff'用來標識檔案的位元組序

另外兩種讀取csv檔案的方法:

#  namedtuple()相等於建立了乙個student型別的類 需要匯入模組

def csv_namedtuple_read():
with open("student.csv", encoding="utf-8-sig") as f:
content = csv.reader(f)
header = next(content)
student = namedtuple("student", header)
for row in content:
stu = student(*row)
print(stu)
# 讀取csv到字典表中
def csv_dict_read():
with open("student.csv", encoding = "utf-8-sig") as f:
students = csv.dictreader(f)
for stu in students:
print(stu)
