  3. "3) JAVA! " comes because "JAVA!" is the upper case letter of "java!" which is the value of "y" variable and "y.toUpperCase( )" statement change the value from lower case to uppercase of the value of "y" variable which is stored on "c" variable and "c" will be printed with "3)" symbol.

Ideally, how often should you back up the data on your computer? once an hour once a day once a month once a year
AleksAgata [21]
It really depends on your type of data, if it's sensitive data or not. And it also depends on what type of backup (Incremental, Decremental, etc.). But you should aim to backup at least once a week, and also do a backup of your original backup.

natima [27]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The given Python code is:

>>> A = ['dog''red']

>>> B = [' cat', 'blue']

>>>C = ['fish', 'green']

We can implement an array of this data by using the dictionary in Python.

Dictionary in python:

A dictionary in python stores (key-value) pairs. For example, we can implement the -given arrays A, B, and C in the dictionary as given below:

d={'dog : red', 'cat : blue', 'fish : green'}

print(d['dog']) # Get an entry from a dictionary; prints "red"

print('cat' in d)    # Check if a dictionary has a given key; prints "True"

d['fish'] = 'black'    # Set an entry in a dictionary

print(d['fish'])      # Prints "black"

# print(d['elephant'])  # KeyError: 'elephant' not a key of d

print(d.get('elephant', 'N/A'))  # Get an element with a default; prints "N/A"

print(d.get('fish', 'N/A'))   # Get an element with a default; prints "black"

del d['dog']        # Remove an element from a dictionary

print(d.get('dog', 'N/A')) # "dog" is no longer a key; prints "N/A"
