打印包含字符串和其他两个变量的变量

var_a = 8
var_b = 3

var_c = "hello my name is:",var_a,"and",var_b,"bye"
print(var_c)

When I run the program var_c gets printed out like this: ('hello my name is:', 8, 'and', 3, 'bye') but all the brackets etc get printed as well, why is this and is there a way to get rid of those symbols?

当我运行这个程序时，var_c会像这样打印出来:(“你好，我的名字是:”，8，“，”，3，“bye”)，但是所有的方括号等都打印出来了，为什么会这样，有没有办法去掉这些符号呢?

If I run the program like this:

如果我像这样运行程序:

print("hello my name is:",var_a,"and",var_b,"bye")

I don't have that problem

我没有这个问题。

8 个解决方案

#1

In Python 3.6+ you can use the new f-strings (formatted string literals):

在Python 3.6+中，您可以使用新的f-string(格式化字符串):

var_c = f"hello my name is: {var_a} and {var_b}, bye"

#2

You can format your string to get your expected string output.

您可以格式化您的字符串以获得预期的字符串输出。

var_c = "hello my name is: {} and {}, bye".format(var_a, var_b)

As commented, your existing output is due to the variable being returned as a tuple, whereas you want it as one string.

如前所述，您现有的输出是由于变量作为元组返回，而您希望它作为一个字符串返回。

#3

var_c is actually a tuple, so print interprets it like that and you get its representation printed.

var_c实际上是一个元组，所以print这样解释它，你就可以打印它的表示。

var_a = 8
var_b = 3
var_c = "hello my name is:", var_a, "and", var_b, "bye"

but you could just tell print to use the tuple as arguments with *

但是您可以告诉print使用tuple作为与*的参数

print(*var_c)

result:

结果:

hello my name is: 8 and 3 bye

(of course this is theorical, it's better to use str.format as other answers said)

(当然这是理论上的，最好像其他答案说的那样使用str.format)

#4

You should create var_c as a string, like this

您应该像这样创建var_c作为字符串。

var_c = "hello my name is: %s and %s bye" % (var_a, var_b)

#5

var_c = "hello my name is:",var_a,"and",var_b,"bye"

with this line, you are making var_c as tuple... to make it string make it like

使用这一行，您将var_c创建为tuple…让它像绳子一样

var_d = "hello my name is:%s and %s bye" % (var_a,var_b)
print(var_d)

and it will output

它会输出

hello my name is:8 and 3 bye

#6

Your program is creating a tuple and you print the tuple:

您的程序正在创建一个tuple并打印tuple:

var_a = 8
var_b = 3

var_c = "hello my name is:", var_a, "and", var_b, "bye"
print(var_c)

output:

输出:

('hello my name is:', 8, 'and', 3, 'bye') 

Alternatively print like this:

或者打印:

for item in var_c:
    print(item+' ', end='')

output:

输出:

hello my name is: 8 and 3 bye

#7

That's because you are using syntax to create a tuple!

这是因为您正在使用语法创建一个tuple!

tup = "a", "b", "c", "d"

If you just want to concatenate these you can write:

如果你只是想把这些连接起来，你可以这样写:

var_c = "hello my name is: " + str(var_a) + " and " + str(var_b) + " bye"

#8

var_a = 8
var_b = 3

var_c = "hello my name is:", var_a, "and", var_b, "bye"
print(var_c)

output:

输出:

('hello my name is:', 8, 'and', 3, 'bye') 

Alternatively print like this:

或者打印:

for item in var_c:
    print(item+' ', end='')

output:

输出:

hello my name is: 8 and 3 bye
