为了在dataframe中查找序列,可以使用循环结构来遍历数据框的每一行或每一列,并检查是否存在所需的序列。以下是一个示例代码,演示了如何使用While-loop在dataframe中查找序列: 代码语言:txt 复制 import pandas as pd # 创建一个示例dataframe data = {'A': [1, 2, 3, 4, 5], 'B': [6, 7, 8, 9, ...
python pandas while-loop 我有一个while循环,它从一个列表中随机返回三个项目。然后再这样做,直到列表为空。我想在pandas数据帧中收集所有这16行。 from random import randint colors = ['Pink', 'Purple', 'Green', 'Skyblue', 'Blue', 'Grey'] * 8 while colors: lst = [colors.pop(randint(0, l...
这是 while 循环: while np.any(i >= SDhigh for i in minutes): #used to be >=, it doesnt matter for the outcome trainsData = trainsData[trainsData['duration_minutes'] < SDhigh] #used to be >=, this caused an infinite loop so I changed it to <=. Then to < minutes = trainsD...
