您应该能够使用格式方法：
"Location: {0:20} Revision {1}".format(Location, Revision)
您必须根据标签的长度计算出每行的格式长度。该User行将需要比LocationorDistrict行更宽的格式宽度。
尝试%*s并%-*s在每个字符串前面加上列宽：
>>> 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来指定制表位，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))
输出：
Location: 10-10-10-10 Revision: 1
District: Tower Date: May 16, 2012
从 Python 3.6 开始，我们有一个更好的选择，f-strings！
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
由于大括号内的所有内容都是在运行时评估的，因此我们可以输入'Location: '与变量连接的字符串location。Using:<25将整个连接的字符串放入一个 25 个字符长的框中，并<指定您希望它左对齐。这样，第二列总是在为第一列保留的 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。使用 25 将适用于所有这些，前提是 25 的长度足以包含左列中的所有字符。
https://realpython.com/python-f-strings/解释了 f-strings 相对于以前的选项的好处。 https://medium.com/@NirantK/best-of-python3-6-f-strings-41f9154983e解释了如何使用 <、> 和 ^ 进行左对齐、右对齐和居中对齐。
@IronMensan 的格式方法答案是要走的路。但为了回答您关于 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
编辑注意这个方法不需要你知道你的字符串有多长。.format() 也可能，但我对它还不够熟悉。
>>> 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'
复活另一个话题，但这对某些人来说可能会派上用场。
从https://pyformat.info获得一点启发，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
