在python列表中搜索子字符串，然后将其从lis中删除

Question

我有一个python列表，比如：

['A /cloudos-ui/branches/bare_metal', 
'M /cloudos-ui/branches/bare_metal/packaging/DEBIAN/control', 
'M /cloudos-ui/branches/bare_metal/create_cosmos_installer.sh', 
'M /cloudos-ui/branches/bare_metal/packaging/DEBIAN/control', 
'M /cloudos-ui/branches/bare_metal/scripts/create_skyline_installer.sh', 
'M /cloudos-ui/branches/bare_metal/forms.py', 
'M /cloudos-ui/branches/bare_metal/tables.py', 
'M /cloudos-ui/branches/bare_metal/templates/flavors/_create.html',
'M /cloudos-ui/branches/bare_metal/templates/flavors/_edit.html',
'A /cloudos-ui/branches/bare_metal/scripts/create_skyline_installer.sh',
'A /cloudos-ui/branches/bare_metal/forms.py', 
'A /cloudos-ui/branches/bare_metal/tables.py', 
'A /cloudos-ui/branches/bare_metal/templates/flavors/_create.html']

现在每个字符串的第一个字符是A或M。除了第一个字母外，有些字符串是相同的：例如，以create_skyline_installer.sh结尾的两个字符串，从顶部起第5个，从底部起第4个。你知道吗

现在我要实现的是找到在A或M之后，字符串主体的其余部分相同的字符串。然后我想删除以M开头的list元素。你知道吗

我是说最后的清单应该是这样的：

['A /cloudos-ui/branches/bare_metal', 
'M /cloudos-ui/branches/bare_metal/packaging/DEBIAN/control', 
'M /cloudos-ui/branches/bare_metal/create_cosmos_installer.sh', 
'M /cloudos-ui/branches/bare_metal/packaging/DEBIAN/control', 
'M /cloudos-ui/branches/bare_metal/scripts/create_skyline_installer.sh',
'M /cloudos-ui/branches/bare_metal/forms.py', 
'M /cloudos-ui/branches/bare_metal/tables.py', 
'M /cloudos-ui/branches/bare_metal/templates/flavors/_create.html',
'M /cloudos-ui/branches/bare_metal/templates/flavors/_edit.html']

但我找不到解决办法。你知道吗

请帮帮我。你知道吗

尝试对列表进行排序，其中A元素将在M元素之前进行处理，并使用字典保存它们，因此第一个条目将被覆盖。使用reverse=True保留A条目。你知道吗

lst = ['A /cloudos-ui/branches/bare_metal (from /cloudos-ui/branches/rc4g1build:9930)',                            
'M /cloudos-ui/branches/bare_metal/misc/cosmos/packaging/DEBIAN/control', 
'M /cloudos-ui/branches/bare_metal/misc/cosmos/scripts/create_cosmos_installer.sh', 
'M /cloudos-ui/branches/bare_metal/misc/skyline/packaging/DEBIAN/control', 
'M /cloudos-ui/branches/bare_metal/misc/skyline/scripts/create_skyline_installer.sh',
'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/forms.py', 
'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/tables.py', 
'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/templates/flavors/_create.html',
'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/templates/flavors/_edit.html',
'A /cloudos-ui/branches/bare_metal/misc/skyline/scripts/create_skyline_installer.sh',
'A /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/forms.py', 
'A /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/tables.py', 
'A /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/templates/flavors/_create.html']

d = {}

for elem in sorted(lst):
    l = elem.split(None, 1)
    d[l[1]] = elem

print(list(d.values()))

它产生：

['A /cloudos-ui/branches/bare_metal (from /cloudos-ui/branches/rc4g1build:9930)',
 'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/templates/flavors/_edit.html',
 'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/forms.py',
 'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/tables.py',
 'M /cloudos-ui/branches/bare_metal/misc/cosmos/packaging/DEBIAN/control',
 'M /cloudos-ui/branches/bare_metal/src/horizon/openstack_dashboard/dashboards/admin/flavors/templates/flavors/_create.html',
 'M /cloudos-ui/branches/bare_metal/misc/skyline/packaging/DEBIAN/control',
 'M /cloudos-ui/branches/bare_metal/misc/cosmos/scripts/create_cosmos_installer.sh',
 'M /cloudos-ui/branches/bare_metal/misc/skyline/scripts/create_skyline_installer.sh']
