如何在python中附加整数
我有这个阵列:如何在python中附加整数,python,python-3.x,Python,Python 3.x,我有这个阵列: listPatients = [[ "Johnson", "Fred", "N", "2763 Filibuster Drive", "Lakeland", "FL", "37643", "Q", "05/27/1935", "164-55-0726", "N"]] \ + [[ "Williams", "Betty", "L", "701 Collage Avenue", "Orlando", "FL", "31234",

我想加上年龄;这是取出生年份(指数(数组(元素[7]))并从2015年减去后的计算:
for patients in range(len(listPatients)):
YOB=listPatients[patients][8][6]+listPatients[patients][8][7]
+listPatients[patients][8][8]+listPatients[patients][8][9]
age= currentYear-int(YOB)
story4=patients.append(age)
输出显示我不能附加整数。我能做什么?在您的代码片段中,
患者
是一个int
,它没有附加
方法
>>> range(len(['x','y','z']))
[0, 1, 2]
范围迭代器中的每个项目都将是一个整数。在您的代码中,
患者
是列表列表中的索引,而不是子列表本身,即使用患者。追加(年龄)
您正试图追加到一个数字!相反,请尝试迭代列表患者
本身。此外,您可以使用切片[6:://code>而不是将年份的所有单个字符串联起来,或者使用患者[8].split('/')[2]
来获取年份
for patients in listPatients:
YOB = patients[8][6:] # or patients[8].split('/')[2]
age = currentYear - int(YOB)
patients.append(age)
另外,append
不会返回任何内容,因此无论story4
应该是什么,它都将始终是None
最后,您可以这样编写多行列表:
listPatients = [[ "Johnson", ... stuff ..., "164-55-0726", "N"],
... many more lines ...
[ "Chaney", ... stuff ..., "963-25-7418", "Y"]]
这里没有理由使用范围
进行迭代
for patient in listPatients:
YOB=patient[8][-4:]
age= currentYear-int(YOB)
patient.append(age)
story4=age
您希望显示listPatients元素,而不是其范围:
for patients in range(len(listPatients)):
YOB=listPatients[patients][8][6]+listPatients[patients][8][7]+listPatients[patients][8][8]+listPatients[patients][8][9]
age= currentYear-int(YOB)
story4=listPatients[patients].append(age)
你能添加完整的回溯吗?我想它说,'int'对象没有属性“append”
在这种情况下,患者不是一个列表。我希望这不是真实的患者数据。@user5402其中一些地址不存在,所以可能不存在。我应该字符串(患者)吗@C.B.@JoshuaPilkinstory4
应该是什么?story4的输出将是我患者的年龄@为什么要投否决票?我自己在OPs数据上运行了这段代码,它运行得非常好。不管谁投了反对票,想解释一下吗?我真的很想让投反对票的人解释一下。这是您可以对代码进行的最简单的更改,以使其正常工作。以最小的努力获得最大的结果。
