Python 从列表中放入具有for循环的函数的参数

名单如下：

li=['check3_dwg_Polyline', 'check2_dwg_Polyline', 
    'check3_dwg_Polyline_feat_to_polyg',# this will not be needed to extracted
    'check2_dwg_Polyline_feat_to_polyg',# >> >>
    'check3_dwg_Polyline_feat_to_polyg_feat_to_line', 
    'check2_dwg_Polyline_feat_to_polyg_feat_to_line']

目的

将参数设置为：

erase('check3_dwg_Polyline','check3_dwg_Polyline_feat_to_polyg_feat_to_line','output_name')

有用信息：尝试对列表排序，但未修复。

其目的是从列表中提取文件，并通过循环将其放入函数

erase

像这样：

erase('check3_dwg_Polyline','check3_dwg_Polyline_feat_to_polyg_feat_to_line','output_name')

我试过：

a=[li[i:i+3] for i in range(0, len(li), 3)]

for base, base_f, base_line in a:
    print(base, base_line, base + "_output") # when it is fixed the 
                                             # print will be replaced with 
                                              # 'erase' to form the function

它给出了：

check2_dwg_Polyline_feat_to_polyg  check2_dwg_Polyline_feat_to_polyg_feat_to_line  check2_dwg_Polyline_feat_to_polyg_output 
check3_dwg_Polyline  check3_dwg_Polyline_feat_to_polyg  check3_dwg_Polyline_output 

虽然它应该：

check3_dwg_Polyline   check3_dwg_Polyline_feat_to_polyg_feat_to_line  check3_dwg_Polyline_output

check2_dwg_Polyline   check2_dwg_Polyline_feat_to_polyg_feat_to_line  check2_dwg_Polyline_output

因此，以后可以将其设置为如下功能：

erase('check3_dwg_Polyline','check3_dwg_Polyline_feat_to_polyg_feat_to_line','output_name')

如果要使用

li

的前3项调用函数

erase

，则应切掉列表的前3项，并使用

apply

调用函数：

def erase(a,b,c):
    #do something with a,b,c
    return

li=['check3_dwg_Polyline', 'check2_dwg_Polyline', 
'check3_dwg_Polyline_feat_to_polyg',
'check2_dwg_Polyline_feat_to_polyg',
'check3_dwg_Polyline_feat_to_polyg_feat_to_line', 
'check2_dwg_Polyline_feat_to_polyg_feat_to_line']

apply(erase,li[:3])

您需要解释这段代码应该做什么，以及它目前做错了什么。您想要什么还不清楚。您能告诉我们您的预期输出和当前输出/错误吗？@FHTMitchell您能建议如何修复它吗？
