Python – How to split string into a dict

Few Python examples to show you how to split a string into a dictionary.

1.1 Split a string into a dict.

#!/usr/bin/python

str = "key1=value1;key2=value2;key3=value3"

d = dict(x.split("=") for x in str.split(";"))

for k, v in d.items():
    print(k, v)

Output

key1 value1
key2 value2
key3 value3

1.2 Convert two list into a dict.

#!/usr/bin/python

str1 = "key1 | key2 | key3"
str2 = "value1 | value2 | value3"

keys = str1.split("|")
values = str2.split("|")

d = {}

for k in keys:
    k = k.strip()         # key trim
    for v in values:
        d[k] = v.strip()  # value trim

for k, v in d.items():
    print(k, v)

Output

key1 value1
key2 value2
key3 value3

1.3 zip example.

#!/usr/bin/python
str1 = "key1 | key2 | key3"
str2 = "value1 | value2 | value3"

keys = str1.split(" | ")
values = str2.split(" | ")

d = dict(zip(keys, values))

for k, v in d.items():
    print(k, v)

Output

key1 value1
key2 value2
key3 value3
