loop through a dict code example
Example 1: python iterate through dictionary
a_dict = {'apple':'red', 'grass':'green', 'sky':'blue'}
for key in a_dict:
print key # for the keys
print a_dict[key] # for the values
Example 2: python loop through dictionary
d = {'x': 1, 'y': 2, 'z': 3}
for key in d:
print key, 'corresponds to', d[key]
Example 3: for key value in dict python
a_dict = {"color": "blue", "fruit": "apple", "pet": "dog"}
for key in a_dict:
print(key, '->', a_dict[key])
# Output:
# color -> blue
# fruit -> apple
# pet -> dog
Example 4: python generate dictionary in loop
n = int(input())
ans = {}
for i in range (1,n+1):
ans[i] = i * i
print(ans)
