我如何使用raw_input和字符串格式化％或％d python

Question

i have variable var, and it is changeable how can i use raw_input and inside raw_input make a question and use this variable ie

z = raw_input("Is your age %d') %(var)

but this don't work. Any ideas?

Answer 1

您的代码应为：

z = raw_input("Is your age %d" %(var,) )

Answer 2

With raw_input , %var should also lie within the parentheses. ie:

z = raw_input("Is your age %d" % var)

Answer 3

我猜最干净的方法是使用format ：

z = raw_input("Is your age {0}?".format(var))
