我正在尝试添加间距以在两个字符串变量之间对齐文本而不使用“”来执行此操作
尝试将文本看起来像这样，第二列对齐。
Location: 10-10-10-10 Revision: 1
District: Tower Date: May 16, 2012
User: LOD Time: 10:15
目前有这样编码，只使用空格......
"Location: " + Location + " Revision: " + Revision + '\n'
我尝试过使用string.rjust＆amp; srting.ljust但无济于事。
建议？

您应该可以使用格式化方法：
"Location: {0:20} Revision {1}".format(Location,Revision)
您必须根据标签的长度找出每行的格式长度。用户线需要比位置或区域线更宽的格式宽度。

尝试%*s和%-*s并为每个字符串添加列宽：
>>> print "Location: %-*s Revision: %s" % (20,"10-10-10-10","1")
Location: 10-10-10-10 Revision: 1
>>> print "District: %-*s Date: %s" % (20,"Tower","May 16, 2012")
District: Tower Date: May 16, 2012

您可以使用expandtabs指定tabstop，如下所示：
>>> print ('Location:'+'10-10-10-10'+'\t'+ 'Revision: 1').expandtabs(30)
>>> print ('District: Tower'+'\t'+ 'Date: May 16, 2012').expandtabs(30)
#Output:
Location:10-10-10-10 Revision: 1
District: Tower Date: May 16, 2012

@ IronMensan的格式方法答案是要走的路。但是为了回答你关于ljust的问题：
>>> def printit():
... print 'Location: 10-10-10-10'.ljust(40) + 'Revision: 1'
... print 'District: Tower'.ljust(40) + 'Date: May 16, 2012'
... print 'User: LOD'.ljust(40) + 'Time: 10:15'
...
>>> printit()
Location: 10-10-10-10 Revision: 1
District: Tower Date: May 16, 2012
User: LOD Time: 10:15
编辑注意此方法不需要您知道字符串的长度。 .format（）也可能，但我不太熟悉它。
>>> uname='LOD'
>>> 'User: {}'.format(uname).ljust(40) + 'Time: 10:15'
'User: LOD Time: 10:15'
>>> uname='Tiddlywinks'
>>> 'User: {}'.format(uname).ljust(40) + 'Time: 10:15'
'User: Tiddlywinks Time: 10:15'

从Python 3.6开始，我们有一个更好的选择，f字符串！
>>> print(f"{'Location: ' + location:<25} Revision: {revision}")
>>> print(f"{'District: ' + district:<25} Date: {date}")
>>> print(f"{'User: ' + user:<25} Time: {time}")
输出：
Location: 10-10-10-10 Revision: 1
District: Tower Date: May 16, 2012
User: LOD Time: 10:15
由于大括号中的所有内容都在运行时进行了评估，因此我们可以输入字符串'Location：'和变量location并置。使用：<25将整个串联的字符串放入一个25个字符长的框中，而<表示您希望它保持左对齐。这样，第二列始终在为第一列保留的那25个字符之后开始。
这里的另一个好处是您不必计算格式字符串中的字符。只要25个字符足以容纳左栏中的所有字符，就可以使用25个字符。
https://realpython.com/python-f-strings/解释了f字符串相对于先前选项的好处。 https://medium.com/@NirantK/best-of-python3-6-f-strings-41f9154983e解释了如何使用<，>和^进行左，右和居中对齐。

复活另一个主题，但这对某些人可能会派上用场。
从https://pyformat.info中得到一点启发，您可以构建一种方法来获取目录[TOC]样式的打印输出。
# Define parameters
Location = '10-10-10-10'
Revision = 1
District = 'Tower'
MyDate = 'May 16, 2012'
MyUser = 'LOD'
MyTime = '10:15'
# This is just one way to arrange the data
data = [
['Location: '+Location, 'Revision:'+str(Revision)],
['District: '+District, 'Date: '+MyDate],
['User: '+MyUser,'Time: '+MyTime]
]
# The 'Table of Content' [TOC] style print function
def print_table_line(key,val,space_char,val_loc):
# key: This would be the TOC item equivalent
# val: This would be the TOC page number equivalent
# space_char: This is the spacing character between key and val (often a dot for a TOC), must be >= 5
# val_loc: This is the location in the string where the first character of val would be located
val_loc = max(5,val_loc)
if (val_loc <= len(key)):
# if val_loc is within the space of key, truncate key and
cut_str = '{:.'+str(val_loc-4)+'}'
key = cut_str.format(key)+'...'+space_char
space_str = '{:'+space_char+'>'+str(val_loc-len(key)+len(str(val)))+'}'
print(key+space_str.format(str(val)))
# Examples
for d in data:
print_table_line(d[0],d[1],' ',30)
print('\n')
for d in data:
print_table_line(d[0],d[1],'_',25)
print('\n')
for d in data:
print_table_line(d[0],d[1],' ',20)
结果输出如下：
Location: 10-10-10-10 Revision:1
District: Tower Date: May 16, 2012
User: LOD Time: 10:15
Location: 10-10-10-10____Revision:1
