Populating a dictionary using for loops (python)
PythonDictionaryPython Problem Overview
I'm trying to create a dictionary using for loops. Here is my code:
dicts = {}
keys = range(4)
values = ["Hi", "I", "am", "John"]
for i in keys:
for x in values:
dicts[i] = x
print(dicts)
This outputs:
{0: 'John', 1: 'John', 2: 'John', 3: 'John'}
Why?
I was planning on making it output:
{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}
Why doesn't it output that way and how do we make it output correctly?
Python Solutions
Solution 1 - Python
dicts = {}
keys = range(4)
values = ["Hi", "I", "am", "John"]
for i in keys:
dicts[i] = values[i]
print(dicts)
alternatively
In [7]: dict(list(enumerate(values)))
Out[7]: {0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}
Solution 2 - Python
>>> dict(zip(keys, values))
{0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}
