						这篇文章主要介绍了Python csv模块使用方法代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下





import csv

def openSCV(filename):

  with open("renting.csv",'r',encoding = 'utf_8_sig') as f:

    f_csv = csv.reader(f)

    for row in f_csv:

      print(row)

def Test1():

  headers = ['ID','NAME','Age','Height']

  #表格内容

  rows = [('1','LiLi',18,165),('2','Jack',20,170),('3','Marry',21,168)]

  with open('test1.csv','w',encoding='utf_8_sig') as csvfile:

    spamwriter = csv.writer(csvfile)

    spamwriter.writerow(headers)

    spamwriter.writerows(rows)

def writeDict():

  with open('test2.csv','w') as csvfile:

    #创建字段名

    fieldnames = ['first_name','last_time']

    #创建字段写入对象

    writer = csv.DictWriter(csvfile,fieldnames=fieldnames)

    writer.writeheader()

    #写入表格内容

    writer.writerow({'first_name':'Baked','last_time':'Beans'})

    writer.writerow({'first_name': 'Baked', 'last_time': 'Beans'})

    writer.writerow({'first_name': 'Baked', 'last_time': 'Beans'})

def readDict():

  with open('test2.csv','r') as csvfile:

    #读取文件

    reader = csv.DictReader(csvfile)

    #遍历输入指定字段的内容

    for row in reader:

      print(row['first_name'],row['last_time'])

if __name__ == '__main__':

  Test1()

  writeDict()

  readDict()
