在读取CSV文件时,可以指定编码格式为utf-8,如下所示:pythonCopy code import csv with open('file...
以下是一个简单的Python脚本示例,用于将GBK编码的CSV文件转换为UTF-8编码:import csvimport codecsdef convert_csv_encoding(input_file, output_file, input_encoding='gbk', output_encoding='utf-8'): with codecs.open(input_file, 'r', encoding=input_encoding) as file_in: with codecs.open(...

需要安装Python环境 对非技术用户不太友好 这里我给大家提供一个简单的Python脚本示例:import csvimport codecsdef convert_encoding(input_file, output_file, from_encoding='gbk', to_encoding='utf-8'): try: # 打开输入文件 with codecs.open(input_file, 'r', encoding=from_encoding) as fil...

首先,我们需要使用Python的csv模块来读取CSV文件。下面是读取CSV文件的代码示例: importcsvdefread_csv_file(file_path):withopen(file_path,'r')asfile:reader=csv.reader(file)forrowinreader:# 处理每一行的数据process_row_data(row) 1. 2. 3.
import csv students = [] with open("names.csv") as file: reader = csv.reader(file) for row in reader: students.append({'name': row[0], 'class1': row[1]}) ## get_class -> lambda fuction for student in sorted(students, key=lambda student: student['class1'], reverse=True): ...
