1) The document contains a student's experiment details including their name, roll number, batch, experiment number, title, algorithm, flow chart, Python code, and output. 2) The experiment compares two strings and converts one string to the opposite case by looping through each character, determining its ASCII value, and adding or subtracting 32 to convert between upper and lower case. 3) The Python code takes a user input string, initializes an empty string, loops through each character of the input string, calculates the new ASCII value, converts it to a character, and adds it to the output string which is then printed.

1. Name of Students Omkar Rane
Roll No D422
Batch D1
Experiment No EX-7-2
Title of Experiment
EX-7.2: Compare two strings and convert in opposite case in
Python.
Write An Algorithm:
Step1)start
Step2) Take the string from user i.e str1
Step 3) Declare the empty string i.e str1=””
Step4) loop: q=initial character to q=end char
Read the ascii value of q i.e code
If code>=92 and
Then
Add 32 in code
Else
Then
Sub 32 in code
LoopEnd
Step 5:
Read character value m of ascii
step6) str1=str2+j
step10) Display str1
step11) stop
Flow Chart:

2. Paste Your Python Program ( Python Code):
str1=raw_input("Enter string:") # Enter string for conversion
print str1 # blank string
str2=""
for q in str1: #looping
c=ord(q)
if(c>=92):
m=c-32
else:
m=c+32
j=chr(m)
str2=str2+j
print str2
Paste Your Program OUTPUT :
