Python 遍历电子表格的每一行

Question

我有一个如下所示的数据框:

我编写了一个函数来分解每个时间戳并计算停机时间和运行时间之间的分钟数。我无法让它对每一行进行迭代。

data1 = str(list(data['Adjusted_Down']))
data2 = str(list(data['Adjusted_Up']))
breakdown(data1, data2)

引用代码:

import pandas as pd

data = pd.read_excel('E:\Savers\Python\Python3 - Master\lab.xlsx')

def breakdown(x, y):
    string1 = x.split()
    variable1 = string1[0]
    dateVariable = variable1.split('-')
    variable2 = string1[1]
    dateVariable2 = variable2.split(':')
    hour = int(dateVariable2[0])
    minute = int(dateVariable2[1])
    seconds = int(dateVariable2[2])

    string1B = y.split()
    variable1B = string1B[0]
    dateVariableB = variable1B.split('-')
    variable2B = string1B[1]
    dateVariable2B = variable2B.split(':')
    hourB = int(dateVariable2B[0])
    minuteB = int(dateVariable2B[1])
    secondsB = int(dateVariable2B[2])

    if hourB > hour:
        sumMinutes = (hourB - hour)*60
        sumMinutes = sumMinutes + (minuteB - minute)
        print(sumMinutes)
    elif hourB == hour:
        sumMinutes = (minuteB - minute)
        print(sumMinutes)

Answer 1

我的假设是您想为数据 df 中的每一行运行 breakdown() 函数

for index, row in data.iterrows():
    data1 = str(row['Adjusted_Down'])
    data2 = str(row['Adjusted_Up'])
    breakdown(data1, data2)
