EXERCISE - 5 DATA STRUCTURES

5 A) Write a program to count the number of characters in the string and store them in a dictionary data structure.

B) Write a program to use split and join methods in the string and trace a birthday with a dictionary data structure.

A) AIM: Write a program to count the number of characters in the string and store them in a dictionary data structure.

SOURCE CODE:

str1=input("Enter String:\n")
dict1={}
for ch in str1:
    keys=dict1.keys()
    if(ch in keys):
        dict1[ch]=dict1[ch]+1
    else:
        dict1[ch]=1
print("Dictionary is:\n",dict1)

OUTPUT:

Enter String:
hello world
Dictionary is:
{'h': 1, 'e': 1, 'l': 3, 'o': 2, ' ': 1, 'w': 1, 'r': 1, 'd': 1}

B) AIM: Write a program to use split and join methods in the string and trace a birthday with a dictionary data structure.

SOURCE CODE:

bdaystr=input("Enter date of birth:\n")
bdaylist=bdaystr.split("/")
bday='-'.join(bdaylist)
bdaydict={"birthday":bday}
if 'birthday' in bdaydict:
    print(bdaydict['birthday'])

OUTPUT:

Enter date of birth:
01/01/2017
01-01-2017
