ETE2 .phonehome（）它是复活节彩蛋吗？

Question

ETE2（用于系统发育树探索的Python环境）有一个方法.phonehome()，可以在树/节点类对象上调用。这将返回：

== Calling home... Got answer!

He11o alien,
How is everything in the Earth?
We miss you in Brodo Asogi.

I see you are in shape.
No updates are available.

== Do you want to leave any message?
(Press enter to finish)

如果您想亲自测试一下，请尝试：

from ete2 import Tree
t = Tree()      # generate random Tree
t.phonehome()   # communicate with Aliens!

这是一个复活节彩蛋吗？

Answer 1

project logo是：

所以你可以称之为复活节彩蛋。但它也有一个真正的目的，因为它是项目版本检查方法，以一点点幽默命名：

''' I use this module to check for newer versions of ETE '''

和

def call():
    print "  == Calling home...",
    try:
        f = url.urlopen('http://ete.cgenomics.org/et_phone_home.php?VERSION=%s&ID=%s' 
                %(__VERSION__, __ETEID__))

和

if not latest:
    print "I could not find data about your version [%s]" %module_name
    print "Are you ok?"
elif not current:
    print "I could not determine your version [%s]" %module_name
    print "Are you ok?"
    print "Latest stable ETE version is", latest
elif latest > current:
    print "You look a bit old."
    print "A newer version is available: rev%s" %latest
    print "Use 'easy_install -U %s' to upgrade" %module_name
else:
    print "I see you are in shape."
    print "No updates are available."
