nested loops python code example

Example 1: dict comprehension python

# dict comprehension we use same logic, with a difference of key:value pair
# {key:value for i in list}

fruits = ["apple", "banana", "cherry"]
print({f: len(f) for f in fruits})

#output
{'apple': 5, 'banana': 6, 'cherry': 6}

Example 2: how to create a nested loop in python

for i in range(5):
  for j in range(i):
    # you can add many for loops or you can just write any code

Example 3: dict comprehension python

keys=['var1','var2','var3']
my_dict={key:np.zeros(10) for key in keys}
