禁止以python 3 str.format打印换行符 [英] Suppress print newline in python 3 str.format

问题描述

我正在使用Python 3，并尝试将我的打印语句与str.format一起使用.

I am using Python 3 and am trying to use my print statements with the str.format.

例如:

print ('{0:3d} {1:6d} {2:10s} '.format (count1,count2,string1)) 

当我尝试使用end=''禁止显示后续换行符时，将忽略此内容.换行总是发生.

When I try to use the end='' to suppress the subsequent newline, this is ignored. A newline always happens.

如何取消后续的换行符?

How do I suppress the subsequent newline?

print ('newline')
print ( '{0:3d} {1:6d} {2:10s} '.format (int1,int2,string1,end=''))
print ('newline')

推荐答案

您的问题是您将end=''参数传递给了format函数，而不是传递给了print函数.

Your problem is that you have the end='' argument being passed to the format function, not to the print function.

更改此行:

print ( '{0:3d} {1:6d} {2:10s} '.format (int1,int2,string1,end=''))

对此:

print ( '{0:3d} {1:6d} {2:10s} '.format (int1,int2,string1), end='')

顺便说一句，您还应该阅读 PEP8 .它定义了Python编码样式的标准，除非您正在与一群已就其他样式标准达成协议的人员合作，否则您确实应该遵循这些标准.特别是，函数调用之间的间距有些奇怪-函数名称与参数括号之间或括号与第一个参数之间不应有空格.我以保持您当前风格的方式写出了针对您问题的建议解决方案，但实际上它看起来应该更像这样:

By the way, you should also give PEP8 a read. It defines standards for Python coding styles, that you really should try to follow, unless you're working with a group of people that have agreed on some other style standards. In particular, your spacing is a bit weird around function calls - you shouldn't have spaces between function names and the argument parentheses, or between the parentheses and the first argument. I wrote my suggested solution to your problem in a way that maintains your current style, but it really should look more like this:

print('{0:3d} {1:6d} {2:10s} '.format(int1, int2, string1), end='')
