步骤1:打开CSV文件 首先,我们需要打开CSV文件以便读取内容。我们可以使用open函数来打开文件,并且使用csv.reader来读取文件内容。 importcsv# 打开CSV文件withopen('file.csv','r')asfile:csv_reader=csv.reader(file) 1. 2. 3. 4. 5. 步骤2:读取文件内容 接下来,我们可以通过迭代csv_reader来读取文件内容,...
file=open('file.csv','r') 1. 其中,file.csv是要读取的文件路径,'r'表示以只读模式打开文件。如果要以写入模式打开文件,则需要将模式参数设置为'w'。 读取CSV文件 打开文件后,我们可以使用文件对象的read方法来读取文件的内容。对于CSV文件,常见的读取方式有两种:逐行读取和按列读取。 逐行读取 逐行读取是最...
read(size=-1) size表示读取的多少个字符或字节;负数或者None表示读取到EOF filename ='o:/test.txt' f =open(filename,'w+') f.write('你好python') f.close() f =open(filename) print(1, f.read(1))# 按字符 print(2, f.read(2)) print(3, f.read()) f.close() f =open(filename,...
咱们先构造一个无表头的 csv 文档,这里一共有两列,每列之间用“,” comma 逗号分割开来。 1. 逐行打印, 用 row 去接收split(',') with open("names.csv", 'r') as file: for line in file: row = line.rstrip().split(',') print(f"student{row[0]} is in {row[1]}") 这里我们用 split...
