[英]Python: print array of strings to stdout line by line
I need to print to stdout (but next step is print to file) an array of strings, containing the info to build-up a shape. 我需要打印到标准输出(但下一步是打印到文件)一个字符串数组,其中包含建立形状的信息。 Below, the for loop:
下面是for循环:
for i in range(0, xMax):
for j in range(0, yMax):
print arena_shape[ j + i*yMax]
print('\r')
The array arena_shape[] contains the chars to built-up a 2D figure, figure with i = [0, xMax] rows and j = [0, yMax] columns. 数组arena_shape []包含用于构建2D图形的字符,该图形具有i = [0,xMax]行和j = [0,yMax]列。 I expect the output to be :
我希望输出为:
i=0 ---------- ------
i=1 | |
| |
| |
| |
| |
| |
i=xMax --------------------
instead to get the first line (i=0, j=[0,yMax])
in "horizontal" as I would expect, I get it displayed in vertical, even if I tell python to \\r
only when changing row i
and not at each column j
而是像我期望的那样,在“水平”中获得第一行
(i=0, j=[0,yMax])
,我将它显示为垂直,即使我仅在更改row i
而不是告诉python到\\r
时也是如此在每column j
i=0 -

I don't understand why this is not changing line after the print("\\r")
instruction. 我不明白为什么在
print("\\r")
指令后这行没有改变。 Thank you in advance for the help. 预先感谢您的帮助。
The print
function in Python always prints in a new line. Python中的
print
功能始终在新行中打印。 If you want to print without a new line i suggest storing what you need to print in a temporary variable and printing it only when you exit the inner for
loop 如果您想在没有换行的情况下进行打印,建议您将需要打印的内容存储在一个临时变量中,并仅在退出内部
for
循环时才进行打印
for i in range(0, xMax):
temp_variable = ''
for j in range(0, yMax):
temp_variable += arena_shape[ j + i*yMax]
print temp_variable
