Question 14

Question:

Write a program that accepts a sentence and calculate the number of upper case letters and lower case letters.

Suppose the following input is supplied to the program:

Hello world!

Then, the output should be:

UPPER CASE 1
LOWER CASE 9

Hints:

In case of input data being supplied to the question, it should be assumed to be a console input.

Main author's Solution: Python 2

s = raw_input()
d = {"UPPER CASE":0, "LOWER CASE":0}
for c in s:
    if c.isupper():
        d["UPPER CASE"]+=1
    elif c.islower():
        d["LOWER CASE"]+=1
    else:
        pass
print "UPPER CASE", d["UPPER CASE"]
print "LOWER CASE", d["LOWER CASE"]

My Solution: Python 3

word = input()
upper,lower = 0,0

for i in word:
    if 'a'<=i and i<='z' :
        lower+=1
    if 'A'<=i and i<='Z':
        upper+=1

print("UPPER CASE {0}\nLOWER CASE {1}".format(upper,lower))

OR

word = input()
upper,lower = 0,0

for i in word:
        lower+=i.islower()
        upper+=i.isupper()

print("UPPER CASE {0}\nLOWER CASE {1}".format(upper,lower))

OR

word = input()
upper = sum(1 for i in word if i.isupper())           # sum function cumulatively sum up 1's if the condition is True
lower = sum(1 for i in word if i.islower())

print("UPPER CASE {0}\nLOWER CASE {1}".format(upper,lower))

OR

# solution by Amitewu

string = input("Enter the sentense")
upper = 0
lower = 0
for x in string:
    if x.isupper() == True:
        upper += 1
    if x.islower() == True:
        lower += 1

print("UPPER CASE: ", upper)
print("LOWER CASE: ", lower)

Question 15

Question:

Write a program that computes the value of a+aa+aaa+aaaa with a given digit as the value of a.

Suppose the following input is supplied to the program:

9

Then, the output should be:

11106

Hints:

In case of input data being supplied to the question, it should be assumed to be a console input.

Main author's Solution: Python 2

a = raw_input()
n1 = int( "%s" % a )
n2 = int( "%s%s" % (a,a) )
n3 = int( "%s%s%s" % (a,a,a) )
n4 = int( "%s%s%s%s" % (a,a,a,a) )
print n1+n2+n3+n4

My Solution: Python 3

a = input()
total,tmp = 0,str()        # initialing an integer and empty string

for i in range(4):
    tmp+=a               # concatenating 'a' to 'tmp'
    total+=int(tmp)      # converting string type to integer type

print(total)

OR

a = input()
total = int(a) + int(2*a) + int(3*a) + int(4*a)  # N*a=Na, for example  a="23", 2*a="2323",3*a="232323"
print(total)
