Question

我有这段代码，可以将用户输入的术语输出到控制台

x = input("Input x: ")
y = input("Input y: ")
z = input("Input z: ")

xS = x.split(", ")
yS = y.split(", ")
zS = z.split(", ")

[print('"{}"'.format(i), end=" ") for i in xS] + [print('"{}"'.format(i), end=" ") for i in yS] + [print('-"{}"'.format(i), end=" ") for i in zS]

输入可以像he, haha, ho ho, he he he一样，当x = he，y = haha, ho ho和z = he he he

时，打印功能输出如下

"he" "haha" "ho ho" -"he he he"

有人知道一种将打印输出（"he" "haha" "ho ho" -"he he he"）分配给变量j的方法吗？

说明编辑：打印输出中的双引号并不表示其为字符串。整个过程基本上是吸收用户输入，将其以,作为分隔符，然后将""添加到每个以"term"结尾的单独术语的开头和结尾，最终被放到与Google类似的搜索引擎中

Answer 1

尝试一下

>>> x = ['he'];y = 'haha, ho ho'.split(',');z = ['he he he']  
>>> x+y+['-']+z  
['he', 'haha', ' ho ho', '-', 'he he he']
>>> var = " ".join(x+y+['-']+z)

输出：

>>> print(var)    
'he haha  ho ho - he he he'

编辑1：

>>> " ".join('"{}"'.format(el) if el is not '-' else el for el in x+y+['-']+z)        
'"he" "haha" " ho ho" - "he he he"'

Answer 2

尝试一下：

x = input("Input x: ")
y = input("Input y: ")
z = input("Input z: ")

xS = x.split(", ")
yS = y.split(", ")
zS = z.split(", ")
j = ('"{}"'.format(' '.join(xS)), '"{}"'.format(' '.join(yS)), '-"{}"'.format(' '.join(zS)))

print (j)

输出：

Input x: ha, ha
Input y: he, he, he
Input z: huh, hih
('"ha ha"', '"he he he"', '-"huh hih"')

Answer 3

您正在尝试使用打印语句来帮助您设置字符串格式。如前所述，print()将始终返回None。相反，您可以按照以下方式格式化字符串：

x = "he"
y = "haha, ho ho" 
z = "he he he"

xS = x.split(", ")
yS = y.split(", ")
zS = z.split(", ")

j = ' '.join([f'"{i}"' for i in xS] + [f'"{i}"' for i in yS] + [f'-"{i}"' for i in zS])

print(j)

这将显示：

"he" "haha" "ho ho" -"he he he"

Answer 4

我建议您先构造字符串然后再打印。

xS = "he"
yS = "haha, ho ho"
zS = "he he he"

j = " ".join( [ '"' + x.strip() + '"' for y in [xS,yS,zS] for x in y.split(',') ] )

print( j )

输出：

'"he" "haha" "ho ho" "he he he"'

将打印功能的输出分配给变量
