# # Question 31
# 
# ### **Question:**
# 
# > **_Define a function which can print a dictionary where the keys are numbers between 1 and 20 (both included) and the values are square of keys._**
# 
# ---
# 
# ### Hints:
# 
# 
# Use dict[key]=value pattern to put entry into a dictionary.Use ** operator to get power of a number.Use range() for loops.

def printDict():
    dict = {i: i ** 2 for i in range(1, 21)}  # Using comprehension method and
    print(dict)

# # Question 32
# 
# ### **Question:**
# 
# > **_Define a function which can generate a dictionary where the keys are numbers between 1 and 20 (both included) and the values are square of keys. The function should just print the keys only._**
# 
# ---
# 
# ### Hints:
# 
# 
# Use dict[key]=value pattern to put entry into a dictionary.Use ** operator to get power of a number.Use range() for loops.Use keys() to iterate keys in the dictionary. Also we can use item() to get key/value pairs.

# # Question 33
# 
# ### **Question:**
# 
# > **_Define a function which can generate and print a list where the values are square of numbers between 1 and 20 (both included)._**
# 
# ---
# 
# ### Hints:
# 
# 
# Use ** operator to get power of a number.Use range() for loops.Use list.append() to add values into a list.

# # Question 34
# 
# ### **Question:**
# 
# > **_Define a function which can generate a list where the values are square of numbers between 1 and 20 (both included). Then the function needs to print the first 5 elements in the list._**
# 
# ---
# 
# ### Hints:
# 
# 
# Use ** operator to get power of a number.Use range() for loops.Use list.append() to add values into a list.Use [n1:n2] to slice a list

# ### Comment
# 
# **_Problems of this section is very much easy and all of those are of a modification of same type problem which mainly focused on using some commonly used function works with list,dictionary, tupple.In my entire solutions, I havn't tried to solve problems in efficient way.Rather I tried to solve in a different way that I can.This will help a beginner to know how simplest problems can be solved in different ways._**
