在 Python 中打印多个参数

Print multiple arguments in Python

提问by user1985351

This is just a snippet of my code:

这只是我的代码片段：

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

But I want it to print out:

但我希望它打印出来：

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

“（姓名）的总分是（分数）”

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

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

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

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

1. Pass it as a tuple:

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

1. 将其作为元组传递：

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

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

具有单个元素的元组看起来像('this',).

Here are some other common ways of doing it:

以下是其他一些常见的方法：

1. Pass it as a dictionary:

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

2. 将其作为字典传递：

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

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

还有新样式的字符串格式，这可能更容易阅读：

1. Use new-style string formatting:

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

2. 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))
   

3. Use new-style string formatting with explicit names:

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

4. Concatenate strings:

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

3. 使用新式字符串格式：

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

4. 使用带有数字的新型字符串格式（对于重新排序或多次打印相同的数字很有用）：

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

5. 使用带有显式名称的新型字符串格式：

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

6. 连接字符串：

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

The clearest two, in my opinion:

在我看来，最清楚的两个：

1. Just pass the values as parameters:

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

   If you don't want spaces to be inserted automatically by printin the above example, change the sepparameter:

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

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

   from __future__ import print_function
   

2. Use the new f-string formatting in Python 3.6:

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

7. 只需将值作为参数传递：

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

   如果您不希望print在上面的示例中自动插入空格，请更改sep参数：

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

   如果您使用的是 Python 2，将无法使用最后两个，因为print它不是 Python 2 中的函数。但是，您可以从__future__以下位置导入此行为：

   from __future__ import print_function
   

8. f在 Python 3.6 中使用新的-string 格式：

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

Just try:

你试一试：

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

回答by Paolo Rovelli

Keeping it simple, I personally like string concatenation:

保持简单，我个人喜欢字符串连接：

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

It works with both Python 2.7 an 3.X.

它适用于 Python 2.7 和 3.X。

NOTE: If score is an int, then, you should convert it to str:

注意：如果 score 是int，则应将其转换为str：

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

回答by Paolo Rovelli

This is what I do:

这就是我所做的：

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

Remember to put a space after forand before and after is.

请记住在for前后各放一个空格is。

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

%scan be replace by %dor %f

%s可以替换为%d或%f

回答by Supercolbat

If scoreis a number, then

如果score是一个数，那么

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

If score is a string, then

如果 score 是一个字符串，那么

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

If score is a number, then it's %d, if it's a string, then it's %s, if score is a float, then it's %f

如果 score 是一个数字，那么它就是%d，如果它是一个字符串，那么它就是%s，如果 score 是一个浮点数，那么它就是%f

There are many ways to print that.

有很多方法可以打印出来。

Let's have a look with another example.

让我们再看一个例子。

a = 10
b = 20
c = a + b

#Normal string concatenation
print("sum of", a , "and" , b , "is" , c) 

#convert variable into str
print("sum of " + str(a) + " and " + str(b) + " is " + str(c)) 

# if you want to print in tuple way
print("Sum of %s and %s is %s: " %(a,b,c))  

#New style string formatting
print("sum of {} and {} is {}".format(a,b,c)) 

#in case you want to use repr()
print("sum of " + repr(a) + " and " + repr(b) + " is " + repr(c))

EDIT :

#New f-string formatting from Python 3.6:
print(f'Sum of {a} and {b} is {c}')

回答by Abhishek

In Python 3.6, f-stringis much cleaner.

在 Python 3.6 中，f-string要干净得多。

In earlier version:

在早期版本中：

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

In Python 3.6:

在 Python 3.6 中：

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

will do.

会做。

It is more efficient and elegant.

它更高效、更优雅。

Just follow this

只要按照这个

idiot_type = "the biggest idiot"
year = 22
print("I have been {} for {} years ".format(idiot_type, years))

OR

或者

idiot_type = "the biggest idiot"
year = 22
print("I have been %s for %s years."% (idiot_type, year))

And forget all others, else the brain won't be able to map all the formats.

忘记所有其他人，否则大脑将无法映射所有格式。

Use: .format():

使用：.format()：

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

Or:

或者：

// Recommended, more readable code

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

Or:

或者：

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

Or:

或者：

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