occurred while trying to extract file(s) to the Python eggcache: Permission denied: root.python-eggs The Python egg cache directory is currently set to: root.python-eggs解决办法：让开发在代码中声明一下环境变量。
最近在使用Python的时候发现有异常，异常内容为python-eggs is writable ……，详细异常如下：usrlocallibpython2.7site-packagessetuptools -24.0.2-py2.7.eggpkg_resources__init__.py:1268: UserWarning: homehduser06.python-eggs is writable by 最后探讨问题，发现是由于权限问题导致，解决办法：cd homehduser06chmod g-wx,o-wx .python-eggs

现在有四项了 shoppingList += shoppingList 现在有七项了 可以直接使用下标语法来获取数组中的数据项 var firstItem = shoppingList 第一项是 Eggs 也可以用下标来改变某个已有索引值对应的数据值: shoppingList = Six eggs 其中的第一项现在是 Six eggs 而不是 Eggs利用下标来一次改变一系列数据值 shoppingList index, value) in shoppingList.enumerate() { print(Item (String(index + 1)): (value)) } Item 1: Six eggs
如果在一个函数的顶部有global eggs的代码，就说明eggs指的是全局变量。或者：如果在函数中，既没有赋值语句，也没有针对它的global语句，是全局变量。 def spam(): eggs = 1000 return eggs spam()1000# 同理局部变量不能使用其他局部变量def ehbio(): eggs = 99 spam() print(eggs ) def spam(): eggs = 0 return eggs ehbio()99spam()0# 全局变量在局部作用域中使用def spam(): print(eggs) eggs = 28spam ()28print(eggs)28# 尽量避免名称相同的局部变量和全局变量def spam(): eggs = spam local print(eggs) # 输出spam local def bacon (): eggs = bacon local print(eggs) # 输出bacon local spam() print(eggs) # 输出bacon local eggs = globalbacon

例：‘What do you like, {0}, {1} or {2}’.format(“spam”, “eggs”, “ham”)结果是’What do you like, spam, eggs, ham’也可以换顺序 ：‘What do you like, {2}, {1} or {0}’.format(“spam”, “eggs”, “ham”)结果是’What do you like, ham , eggs, spam’也可以使用相应的名字‘What do you like, {ham}, {0} or {eggs}’.format(“spam”, eggs=”eggs”, ham=”ham” )结果是’What do you like, ham, spam, eggs’具体格式为：{fieldname!
