1、python读写csv文件
1 import csv
2
3 #读取csv文件内容方法1
4 csv_file = csv.reader(open('testdata.csv','r'))
5 next(csv_file, None) #skip the headers
6 for user in csv_file:
7 print(user)
8
9 #读取csv文件内容方法2
10 with open('testdata.csv', 'r') as csv_file:
11 reader = csv.reader(csv_file)
12 next(csv_file, None)
13 for user in reader:
14 print(user)
15
16 #从字典写入csv文件
17 dic = {'fengju':25, 'wuxia':26}
18 csv_file = open('testdata1.csv', 'w', newline='')
19 writer = csv.writer(csv_file)
20 for key in dic:
21 writer.writerow([key, dic[key]])
22 csv_file.close() #close CSV file
23
24 csv_file1 = csv.reader(open('testdata1.csv','r'))
25 for user in csv_file1:
26 print(user)
2、python读写excle文件
需要先用python pip命令安装xlrd , xlwt库~
1 import xlrd, xlwt #xlwt只能写入xls文件
2
3 #读取xlsx文件内容
4 rows = [] #create an empty list to store rows
5 book = xlrd.open_workbook('testdata.xlsx') #open the Excel spreadsheet as workbook
6 sheet = book.sheet_by_index(0) #get the first sheet
7 for user in range(1, sheet.nrows): #iterate 1 to maxrows
8 rows.append(list(sheet.row_values(user, 0, sheet.ncols))) #iterate through the sheet and get data from rows in list
9 print(rows)
10
11 #写入xls文件
12 rows1 = [['Name', 'Age'],['fengju', '26'],['wuxia', '25']]
13 book1 = xlwt.Workbook() #create new book1 excle
14 sheet1 = book1.add_sheet('user') #create new sheet
15 for i in range(0, 3):
16 for j in range(0, len(rows1[i])):
17 sheet1.write(i, j, rows1[i][j])
18 book1.save('testdata1.xls') #sava as testdata1.xls
1 import csv
2
3 #读取csv文件内容方法1
4 csv_file = csv.reader(open('testdata.csv','r'))
5 next(csv_file, None) #skip the headers
6 for user in csv_file:
7 print(user)
8
9 #读取csv文件内容方法2
10 with open('testdata.csv', 'r') as csv_file:
11 reader = csv.reader(csv_file)

18 csv_file = open('testdata1.csv', 'w', newline='')
19 writer = csv.writer(csv_file)
20 for key in dic:
21 writer.writerow([key, dic[key]])
22 csv_file.close() #close CSV file

24 csv_file1 = csv.reader(open('testdata1.csv','r'))
