如何批量对字符串进行左，右，中对齐

# # 如何对字符串进行左，右，中对齐
#
# 某字典存储了一系列属性值，
# {
#     'lodDist':100.0,
#     'SmallCull':100.0,
#     'DistCull':100.0,
#     'Trilinear':100.0,
#     'farclip':100.0,
# }
# 在程序中，我们想要以以下工整的格式将其内容输出，如何处理？
# 'lodDist'    : 100.0,
# 'SmallCull'  : 100.0,
# 'DistCull'   : 100.0,
# 'Trilinear'  : 100.0,
# 'farclip'    : 100.0,
