在 Python 中打印多个参数 [英] Print multiple arguments in Python

问题描述

这只是我的代码片段:

print("Total score for %s is %s  ", name, score)

但我想把它打印出来:

(姓名)的总分是(分数)"

"Total score for (name) is (score)"

其中 name 是列表中的变量，score 是整数.如果有帮助的话，这就是 Python 3.3.

where name is a variable in a list and score is an integer. This is Python 3.3 if that helps at all.

推荐答案

有很多方法可以做到这一点.要使用 % 格式修复当前代码，您需要传入一个元组:

There are many ways to do this. To fix your current code using %-formatting, you need to pass in a tuple:

1. 将其作为元组传递:

1. Pass it as a tuple:

print("Total score for %s is %s" % (name, score))

具有单个元素的元组看起来像 ('this',).

A tuple with a single element looks like ('this',).

以下是一些其他常见的做法:

Here are some other common ways of doing it:

1. 将其作为字典传递:

1. Pass it as a dictionary:

print("Total score for %(n)s is %(s)s" % {'n': name, 's': score})

还有新样式的字符串格式，可能更容易阅读:

There's also new-style string formatting, which might be a little easier to read:

1. 使用新样式的字符串格式:

1. Use new-style string formatting:

print("Total score for {} is {}".format(name, score))

使用带有数字的新样式字符串格式(对于重新排序或多次打印相同的数字很有用):

Use new-style string formatting with numbers (useful for reordering or printing the same one multiple times):

print("Total score for {0} is {1}".format(name, score))

使用带有显式名称的新式字符串格式:

Use new-style string formatting with explicit names:

print("Total score for {n} is {s}".format(n=name, s=score))

连接字符串:

Concatenate strings:

print("Total score for " + str(name) + " is " + str(score))

我认为最清楚的两个:

1. 只需将值作为参数传递即可:

1. Just pass the values as parameters:

print("Total score for", name, "is", score)

如果你不希望上面例子中print自动插入空格，修改sep参数:

If you don't want spaces to be inserted automatically by print in the above example, change the sep parameter:

print("Total score for ", name, " is ", score, sep='')

如果您使用的是 Python 2，将无法使用后两个，因为 print 不是 Python 2 中的函数.但是，您可以从 __未来__:

If you're using Python 2, won't be able to use the last two because print isn't a function in Python 2. You can, however, import this behavior from __future__:

from __future__ import print_function

在 Python 3.6 中使用新的 f 字符串格式:

print(f'Total score for {name} is {score}')
