Sample code for iterating through the Dictionary/Json

test_dict = {}
test_dict={'name1':'akku','name2':'basi','name3':'pheeby','name4':'achumon'}

for key in test_dict:
	print("Key is ",key)
	print("Value is ",test_dict[key])
	print("________________")

Sample code for iterating through the Array

test_array = []
test_array=['akku','basi','pheeby']

for name in test_array:
	print("Name is ",name)
	print("________________")

Getting first key without iterating through the dictionary

first_key=next(iter(test_dict))

Example

test_dict = {'key1' : 'value 1', 'key2' : 'value 2', 'key3' : 'value 3'}
first_key = next(iter(test_dict))
first_value=test_dict[first_key]

print("First key is: ",first_key)
print("First Value is: ",first_value)

Sample code to merge two dictionary

def combine_dict(dict1,dict2):
	dict={}
	
	for key in dict1:
		#If there is no key inside combined_cepe
		#Add the data
		if dict.get(key) is None:
			dict[key]=dict1[key]
		else:
			print("Already there is key in dict 1")
			
	for key in dict2:
		#If there is no key inside combined_cepe
		#Add the data
		if dict.get(key) is None:
			dict[key]=dict2[key]
		else:
			print("Already there is key in dict 2")
			
	#Return the combined dict
	return dict

Getting current date

from datetime import datetime

curr_date=datetime.today()
