[人工智能]Python——字符串的对齐问题

# Now we have a src dict as following:
# src_dict = {
# 'David':2000
# 'Jony':12.3
# 'Michel Jackson': 12
# 'MM': 13.2
# }
# we need to get alignment-seted dict as following
# dest_dict = {
# 'David         ':2000
# 'Jony          ':12.3
# 'Michel Jackson': 12
# 'MM'            : 13.2
# }
#

src_dict = {
'David':2000,
'Jony':12.3,
'Michel Jackson': 12,
'MM': 13.2
}
max_len = max(map(len,src_dict.keys() ))
for x in src_dict:
	print(x.ljust(max_len),':', src_dict[x])

运行结果：

David          : 2000
Jony           : 12.3
Michel Jackson : 12
MM             : 13.2
