python字符串嵌套变量问题？

Question

有没有类似于ruby那样的方式 number = 5 “This number is #{number}.“ #=>“This number is 5.“

Answer 1

"This number is %s. " % number

Answer 2

@testcpast 写的是占位符方式已经挺优雅的了，下面还有2种，这样会不会更难看？

用+号不难看？

print "This number is "+ str(number) + "."

用逗号不难看？

print "This number is", number, "."

Answer 3

print "This number is {number}.".format(number=5)

貌似就三楼跟你要的比较类似。
