1. 使用csv模块 Python的标准库中提供了csv模块,使得操作CSV文件变得非常简单。以下是使用csv模块写入CSV文件的基本步骤: 导入csv模块: AI检测代码解析 importcsv 1. 创建CSV文件对象: AI检测代码解析 withopen('data.csv','w',newline='')asfile:writer=csv.writer(file) 1. 2. 使用writerow方法写入一行数据...
defwrite_csv(filename,data):withopen(filename,'w')asfile:writer=csv.writer(file)writer.writerow(data)file.close() 1. 2. 3. 4. 5. 到此为止,我们已经完成了实现一个能够写入CSV文件的Python函数的代码。下面是完整的代码示例: AI检测代码解析 importcsvdefwrite_csv(filename,data):withopen(filenam...
Python provides a dedicated csv module to work with csv files. The module includes various methods to perform different operations. However, we first need to import the module using: import csv Read CSV Files with Python The csv module provides the csv.reader() function to read a CSV file....
reader函数,接收一个可迭代的对象(比如csv文件),能返回一个生成器,就可以从其中解析出csv的内容: 比如下面的代码可以读取csv的全部内容,以行为单位:importcsv import csv with open('enrollments.csv', 'rb') asf: reader =csv.reader(f) enrollments = list(reader) import csv with open('enrollments.csv',...
一、CSV格式: csv是Comma-Separated Values的缩写,是用文本文件形式储存的表格数据。 1.csv模块&reader方法读取: import csv with open('enrollments.csv', 'rb') asf: reader =csv.reader(f) print reader out:<_csv.reader object at 0x00000000063DAF48> ...
