Iterate Over Dictionary

Question

The two setups using print(i, j) and print(i) return the same result. Are there cases when one should be used over the other or is it correct to use them interchangeably?

desc = {'city': 'Monowi', 'state': 'Nebraska', 'county':'Boyd', 'pop': 1}

for i, j in desc.items():
 print(i, j)

for i in desc.items():
 print(i)

---

for i, j in desc.items():
 print(i, j)[1]

for i in desc.items():
 print(i)[1]

Answer 1

Both are different if remove parenthesis in print because you are using python 2X

desc = {'city': 'Monowi', 'state': 'Nebraska', 'county':'Boyd', 'pop': 1}

for i, j in desc.items():
 print i, j 

for i in desc.items():
 print i

output

county Boyd
city Monowi
state Nebraska
pop 1
('county', 'Boyd')
('city', 'Monowi')
('state', 'Nebraska')
('pop', 1)
