讀取csv-第1種方式。
import pandas as pd # 載入pandas套件並命名為pd speed = pd.read_csv("network_speed.csv") # 以read_csv函式讀取csv speed.head(10) # 顯示檔案前10行讀取csv-第2種方式。
import csv # 載入csv套件 # 開啟csv檔案,其中參數newline=""是為了讓資料的換行符號被正確載入,而參數encoding="utf-8"則是因為資料包含中文字元,為了讓中文字元能正確被載入 with open("network_speed.csv",newline="",encoding="utf-8")as file: # 以csv.reader函式讀取資料,若資料的分隔字元非逗號(,),舉例像是冒號(:)則可增加參數delimiter = ":" 來讀取 rows = csv.reader(file) # 以for迴圈將資料一行一行載入 for r in rows: print(r)讀取csv-第2種方式(讀取成Dictionary)。
import csv # 載入csv套件 # 開啟csv檔案,其中參數newline=""是為了讓資料的換行符號被正確載入,而參數encoding="utf-8"則是因為資料包含中文字元,為了讓中文字元能正確被載入 with open("network_speed.cs...取得本站獨家住宿推薦 15%OFF 訂房優惠
