In the next section of QnA String Manipulation in Python Class 11 we will discuss output based questions.

Output Based Questions

Observe the following code and predict the output:

[1] Code 1:

print("""
T
  U
    T
      O
         R
            I
              A
                 L
                   A
                     I
                      C
                        S
                          I
                           P
                           """)

[2] Code 2:

a = str("786")
b = "Python" * 4
print(a,b)
a = a + b
print(len(a))

[3] Code 3:

s="python string fun"
for i in range(0,len(s)):
    if s[i]>='c' and s[i]<='l':
        print(s[i].lower(),end="")
    else:
        print(s[i].upper(),end="")

[4] Code 4:

s="python string fun"
while True:
   if s[0]=='p':
       s = s[3:]
   elif s[-1]=='n':
      s=s[:2]
   else:
      break
print(s)

[5] Code 5:

s="python"
s1=""
s2=""
s3=""
if s[-1]=='n':
    s1 = s[0:3]
    print(s1)
if 'h' in s:
   s2=s[0] + 'i'
   print(s2)
if 'z' not in s:
   s3 = '7' + s[1:] + 'w'
   print(s3)
else:
   s = s* 3
print(s)
