Converting this list into Dictionary using Python

list = ['Name=Sachin\n', 'country=India\n', 'game=cricket\n']

I want this list in a dictionary with keys as Name, country, game and values as Sachin, India, cricket as corresponding values. I got this list using readlines() from a text file.

Use dictionary comprehension:

d = {
        k: v 
        for k, v in map(
                    lambda x: x.strip().split('='), 
                    yourlist
                    )
    }

And as Peter Wood suggested rename your list variable not to shadow the built-in list.

>>> lst = ['Name=Sachin\n', 'country=India\n', 'game=cricket\n']
>>> result = dict(e.strip().split('=') for e in lst)
>>> print(result)
{'Name': 'Sachin', 'country': 'India', 'game': 'cricket'}

The following should work:

my_list = ['Name=Sachin\n', 'country=India\n', 'game=cricket\n']
my_dict = {}

for entry in my_list:
    key, value = entry.strip().split('=')
    my_dict[key] = value

print my_dict

This give you the following dictionary:

{'country': 'India', 'game': 'cricket', 'Name': 'Sachin'}

Note, you should not use a variable name of list as this is used as a Python function.

If you are reading from a file, you could do this is follows:

with open('input.txt', 'r') as f_input:
    my_dict = {}
    for entry in f_input:
        key, value = entry.strip().split('=')
        my_dict[key] = value

print my_dict

answer = {}
with open('path/to/file') as infile:
    for line in infile:  # note: you don't need to call readlines()
        key, value = line.split('=')
        answer[key.strip()] = value.strip()

Just another way using regex.

>>> lis = ['Name=Sachin\n','country=India\n','game=cricket\n']
>>> dict(re.findall(r'(\w+)=(\w+)',''.join(lis)))
{'Name': 'Sachin', 'game': 'cricket', 'country': 'India'}

in one line:

lst =['Name=Sachin\n','country=India\n','game=cricket\n']

dct = dict( (item.split('=')[0], item.split('=')[1].strip()) for item in lst )
print(dct)

# {'game': 'cricket', 'country': 'India', 'Name': 'Sachin'}

note: list ist not a good variable name!

strip() is called twice which is not all that nice - this may be better:

def splt(item):
    sp = item.strip().split('=')
    return sp[0], sp[1]

dct = dict( splt(item) for item in lst )
print(dct)
