Python - 多个％s字符串

Question

如何在python输出中使用多个％s？

TEXT = 'Hi, your first name is %s' %Fname

这很好但是......

TEXT = 'Hi, your first name is %s and your last name is %s' %Fname %Lname

我收到错误

TypeError: not enough arguments for format string

Answer 1

使用元组：

TEXT = 'Hi, your first name is %s and your last name is %s' % (Fname, Lname)

更好：使用str.format(*args, **kwargs)。

"Hi, your first name is {0} and your last name is {1}".format("foo", "bar")

Answer 2

你需要使用元组：

TEXT = 'Hi, your first name is %s', % (Fname)
TEXT = 'Hi, your first name is %s and your last name is %s' % (Fname, Lname)

另外，请考虑使用format()。

Answer 3

TEXT = 'Hi, your first name is %s and your last name is %s' %(Fname, Lname)

或

TEXT ='Hi, your first name is {} and your last name is {}'.format(Fname, Lname)

Answer 4

我喜欢使用字符串格式。

所以

TEXT = 'Hi, your first name is {} and your last name is {}'.format(Fname, Lname)

Answer 5

将所有变量放在元组中，如下所示：

TEXT = 'Hi, your first name is %s and your last name is %s.' %(Fname,Lname)
