在打印中多次使用相同的變量

Question

在Python中，如果我想在打印時使用字符串中的變量，請執行以下操作：

name = "newbie"
site = "Stack Overflow"
print("I, a %s, find %s very useful" % (name, site))

如果我想打印"I, a newbie, find Stack Overflow to be very very very useful'並用變量名替換'very' ，我怎么能這樣做，同時仍然使用name和site變量？

Answer 1

>>> print("I a {0} find {1} {2} {2} {2} {2} useful".format(name, site, 'very'))
I a newbie find stackoverflow very very very very useful

或者，使用名稱：

>>> a='very'
>>> print("I a {name} find {site} {a} {a} {a} {a} useful".format(name=name, site=site, a=a))
I a newbie find stackoverflow very very very very useful

或者，使用本地字典：

>>> print("I a {name} find {site} {a} {a} {a} {a} useful".format(**locals()))
I a newbie find stackoverflow very very very very useful

Answer 2

在python中多次重復任何字符串，您可以輕松地使用*運算符：

word = "very "
print word*3
>>> very very very

所以在給定的上下文中，您可以使用：

print "I %s, find %s %s useful"% ("newbie", "stack", word*3)
>>> I newbie, find stack very very very  useful
