用pandas篩選csv文件內容導出到新csv文件

import pandas as pd

 

df = pd.read_csv(csv_file, encoding="gbk")

new_csv = new_csv_file

 

newdf_list = []

 

for i in range(0,len(df.values)):

    # 獲得單元格值

    value = df.iloc[i,3]

   

    # 篩選條件

    if value <= 1:

        newdf_list.append(df.iloc[i,:])

       

# 將列表轉換爲DataFrame格式

newdf = pd.DataFrame(newdf_list)

newdf.to_csv(new_csv)
