问题:在Python中打印多个参数
这只是我的代码的一部分:
print("Total score for %s is %s ", name, score)
但我希望它打印出来:
“(姓名)的总分是(分数)”
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。
This is just a snippet of my code:
print("Total score for %s is %s ", name, score)
But I want it to print out:
“Total score for (name) is (score)”
where name
is a variable in a list and score
is an integer. This is Python 3.3 if that helps at all.

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:
将其作为元组传递:
print("Total score for %s is %s" % (name, score))
具有单个元素的元组看起来像('this',)
。
这是其他一些常见的实现方法:
将其作为字典传递:
print("Total score for %(n)s is %(s)s" % {'n': name, 's': score})
还有一种新型的字符串格式,可能更容易阅读:
使用新型的字符串格式:
print("Total score for {} is {}".format(name, score))
使用带有数字的新型字符串格式(可用于重新排序或多次打印相同的字符):
print("Total score for {0} is {1}".format(name, score))
使用具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))
连接字符串:
print("Total score for " + str(name) + " is " + str(score))
我认为最清楚的两个是:
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,将不能使用最后两个,因为print
这不是Python 2中的函数。不过,您可以从__future__
以下方式导入此行为:
from __future__ import print_function
f
在Python 3.6中使用新的-string格式:
print(f'Total score for {name} is {score}')
There are many ways to do this. To fix your current code using %
-formatting, you need to pass in a tuple:
Pass it as a tuple:
print("Total score for %s is %s" % (name, score))
A tuple with a single element looks like ('this',)
.
Here are some other common ways of doing it:
Pass it as a dictionary:
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:
Use new-style string formatting:
print("Total score for {} is {}".format(name, score))
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))
Use new-style string formatting with explicit names:
print("Total score for {n} is {s}".format(n=name, s=score))
Concatenate strings:
print("Total score for " + str(name) + " is " + str(score))
The clearest two, in my opinion:
Just pass the values as parameters:
print("Total score for", name, "is", score)
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='')
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
Use the new f
-string formatting in Python 3.6:
print(f'Total score for {name} is {score}')

有很多打印方法。
让我们看另一个例子。
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}')
There are many ways to print that.
Let’s have a look with another example.
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}')

使用方法.format()
:
print("Total score for {0} is {1}".format(name, score))
要么:
// Recommended, more readable code
print("Total score for {n} is {s}".format(n=name, s=score))
要么:
print("Total score for" + name + " is " + score)
要么:
`print("Total score for %s is %d" % (name, score))`
Use: .format()
:
print("Total score for {0} is {1}".format(name, score))
Or:
// Recommended, more readable code
print("Total score for {n} is {s}".format(n=name, s=score))
Or:
print("Total score for" + name + " is " + score)
Or:
`print("Total score for %s is %d" % (name, score))`

在Python 3.6中,f-string
它更加干净。
在早期版本中:
print("Total score for %s is %s. " % (name, score))
在Python 3.6中:
print(f'Total score for {name} is {score}.')
会做。
它更高效,更优雅。
In Python 3.6, f-string
is much cleaner.
In earlier version:
print("Total score for %s is %s. " % (name, score))
In Python 3.6:
print(f'Total score for {name} is {score}.')
will do.
It is more efficient and elegant.

保持简单,我个人喜欢字符串连接:
print("Total score for " + name + " is " + score)
它同时适用于Python 2.7和3.X。
注意:如果score是一个int,则应将其转换为str:
print("Total score for " + name + " is " + str(score))
Keeping it simple, I personally like string concatenation:
print("Total score for " + name + " is " + score)
It works with both Python 2.7 an 3.X.
NOTE: If score is an int, then, you should convert it to str:
print("Total score for " + name + " is " + str(score))

你试一试:
print("Total score for", name, "is", score)
Just try:
print("Total score for", name, "is", score)

只要遵循这个
idiot_type = "the biggest idiot"
year = 22
print("I have been {} for {} years ".format(idiot_type, years))
要么
idiot_type = "the biggest idiot"
year = 22
print("I have been %s for %s years."% (idiot_type, year))
忘记所有其他格式,否则大脑将无法映射所有格式。
Just follow this
idiot_type = "the biggest idiot"
year = 22
print("I have been {} for {} years ".format(idiot_type, years))
OR
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.

print("Total score for %s is %s " % (name, score))
%s
可以替换为%d
或%f
print("Total score for %s is %s " % (name, score))
%s
can be replace by %d
or %f
回答 8
用途f-string
:
print(f'Total score for {name} is {score}')
要么
用途.format
:
print("Total score for {} is {}".format(name, score))
Use f-string
:
print(f'Total score for {name} is {score}')
Or
Use .format
:
print("Total score for {} is {}".format(name, score))

如果score
是数字,则
print("Total score for %s is %d" % (name, score))
如果score是一个字符串,则
print("Total score for %s is %s" % (name, score))
如果score是数字,%d
则为,如果是字符串%s
,则为,如果score是浮点型,则为%f
If score
is a number, then
print("Total score for %s is %d" % (name, score))
If score is a string, then
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

这是我的工作:
print("Total score for " + name + " is " + score)
请记住在for
前后放置一个空格is
。
This is what I do:
print("Total score for " + name + " is " + score)
Remember to put a space after for
and before and after is
.
