import openpyxl

list = [] #存放數據的列表
with open(r'F:/data.txt',mode='r',encoding='utf-8') as f: #這裏路徑自行調整
    content = f.readline() # 按行讀取
    while content: #循環最後一句的意義爲當content讀不到行時停止，這樣能一行一行全部讀取
        print(content,end='') #避免換行輸出
        op = content.split() #用op對象存儲，把一行切割成數組，去除空格
        list.append(float(op[0])) #第一列數據下標爲0
        content = f.readline()
print(list) #list爲第一列數據存放的列表

存儲之後就可供我們使用啦
