我正在尝试从Excel文件中导入数据。我想从特定的工作表中导入,并且在该特定的工作表中仅导入某些列。 我使用的代码如下:
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x28079f9d0 UILabel:0x104529b80'Label'.height == 21 (active)>",
"<NSLayoutConstraint:0x2807ac0a0 UILayoutGuide:0x281d9d500'UIViewSafeAreaLayoutGuide'.bottom == UILabel:0x104529b80'Label'.bottom + 17 (active)>",
"<NSLayoutConstraint:0x2807ac140 UILabel:0x104529b80'Label'.top == UILayoutGuide:0x281d9d500'UIViewSafeAreaLayoutGuide'.top + 18 (active)>",
"<NSLayoutConstraint:0x2807ae490 'UIView-Encapsulated-Layout-Height' Jordy.ViewHomeHeader:0x104529790.height == 143 (active)>",
"<NSLayoutConstraint:0x2807ac000 'UIViewSafeAreaLayoutGuide-bottom' V:[UILayoutGuide:0x281d9d500'UIViewSafeAreaLayoutGuide']-(0)-| (active, names: '|':Jordy.ViewHomeHeader:0x104529790 )>",
"<NSLayoutConstraint:0x28079fc50 'UIViewSafeAreaLayoutGuide-top' V:|-(0)-[UILayoutGuide:0x281d9d500'UIViewSafeAreaLayoutGuide'] (active, names: '|':Jordy.ViewHomeHeader:0x104529790 )>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x28079f9d0 UILabel:0x104529b80'Label'.height == 21 (active)>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
我的想法是仅导入列C0080和C0090。我只使用一个,它可以工作但也不会保留列名。 有人可以帮忙吗 谢谢
答案 0 :(得分:0)
您可以尝试以下方法:
xl_file=pd.ExcelFile('C:/Users/e877780/Desktop/DEV/S2_SK_S_06_02_input.xlsx')
sheet1=xl_file.parse("S.06.02")
s2_0602 = sheet1[['C0080','C0090']]
希望有帮助
