Question

我想将循环输出打印到同一行的屏幕上。

我如何以最简单的方式使用Python 3.x

我知道这个问题已经被要求用于Python 2.7，在行的末尾使用逗号，即print I，但我找不到Python 3.x的解决方案。

i = 0 
while i <10:
     i += 1 
     ## print (i) # python 2.7 would be print i,
     print (i) # python 2.7 would be 'print i,'

屏幕输出。

我想要打印的是：

12345678910

Answer 1

来自help(print)：

Help on built-in function print in module builtins:

print(...)
    print(value, ..., sep=' ', end='\n', file=sys.stdout)

    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file: a file-like object (stream); defaults to the current sys.stdout.
    sep:  string inserted between values, default a space.
    end:  string appended after the last value, default a newline.

您可以使用end关键字：

>>> for i in range(1, 11):
...     print(i, end='')
... 
12345678910>>>

请注意，您必须自己print()最终换行符。顺便说一句，你不会在Python 2中使用尾随逗号获得“12345678910”，而是获得1 2 3 4 5 6 7 8 9 10。

Answer 2

* for python 2.x *

使用尾随逗号来避免换行。

print "Hey Guys!",
print "This is how we print on the same line."

以上代码段的输出为

Hey Guys! This is how we print on the same line.

* for python 3.x *

for i in range(10):
    print(i, end="<separator>") # <separator> = \n, <space> etc.

上述代码段的输出将是（<separator> = " "时），

0 1 2 3 4 5 6 7 8 9

Answer 3

类似于已建议的内容，您可以这样做：

print(i,end=',')

输出：0,1,2,3，

Answer 4

您可以执行以下操作：

>>> print(''.join(map(str,range(1,11))))
12345678910

Answer 5

#StandardSQL
WITH landingpages AS (
  SELECT
    fullVisitorId,
    visitID,
    h.page.pagePath AS LandingPage
  FROM
    `project_id.dataset.table`, UNNEST(hits) AS h
  WHERE hitNumber = 1
), 
sales AS (
   SELECT
      fullVisitorId, visitID, SUM(totals.transactions) AS Transactions , (SUM(totals.transactionRevenue)/1000000) AS Revenue
    FROM
      `project_id.dataset.table`
    WHERE
      totals.visits > 0
      AND totals.transactions >= 1
      AND totals.transactionRevenue IS NOT NULL
    GROUP BY fullVisitorId, visitID
)
SELECT 
  LandingPage, 
  SUM(Transactions) AS Transactions, 
  SUM(Revenue) AS Revenue
FROM landingpages 
JOIN sales
ON landingpages.VisitID = sales.VisitID 
AND landingpages.fullVisitorId = sales.fullVisitorId
GROUP BY LandingPage

这将给出输出

print("single",end=" ")
print("line")

对于问题使用

single line

Answer 6

>>> for i in range(1, 11):
...     print(i, end=' ')
...     if i==len(range(1, 11)): print()
... 
1 2 3 4 5 6 7 8 9 10 
>>>

这是如何做到这一点，以便打印不会在下一行的提示后面运行。

Answer 7

让我们举例说明你想在同一行打印0到n的数字。您可以借助以下代码执行此操作。

n=int(raw_input())
i=0
while(i<n):
    print i,
    i = i+1

在输入时，n = 5

Output : 0 1 2 3 4

在同一行上打印新输出
