字符串"k:1“” 处理成字典 {'k':1,'k1':2....}

1、有字符串"k:1|k1:2|k2:3|k3:4" 处理成字典 {'k':1,'k1':2....}

#第一种方法
 
s1 = "k:1|k1:2|k2:3|k3:4"
d = {}
# print(s1)
s2 = s1.split('|')
print(s2)
for n in s2:
    n1 = n.split(":")
    d[str(n1[0])] = n1[1]
print(d)
 
#第二种方法
s1 = "k:1|k1:2|k2:3|k3:4"
d = {}
# print(s1)
s2 = s1.split('|')
print(s2)
for n in s2:
    n1 = n.split(":")
    d.setdefault(n1[0], n1[1])
print(d)
 
#第三种方法;

s1 = "k:1|k1:2|k2:3|k3:4"
d = {}
# print(s1)
s2 = s1.split('|')
print(s2)
for n in s2:
    n1 = n.split(":")
    d[n1[0]] = n1[1]
print(d)
