【python】读取csv文件

#############读取csv文件数据##########################
# import codecs
# import csv
#
# with codecs.open('data/HZ_SYS_MENU.csv', encoding='utf-8-sig') as f:
#     for row in csv.DictReader(f, skipinitialspace=True):
#         print(row)
# f.close()

############读取csv文件并逐行访问数据#######################################
import codecs
import csv

data_rows = []  # 创建一个列表来存储每一行的数据

with codecs.open('data/HZ_SYS_MENU.csv', encoding='utf-8-sig') as f:
    for row in csv.DictReader(f, skipinitialspace=True):
        data_rows.append(row)  # 将每一行的数据添加到列表中

# 现在可以逐行访问数据
for index, row in enumerate(data_rows):
    print(f"第 {index + 1} 行数据: {row}")
