1. Write a method COUNTLINES() in Python to read lines from text file ‘TESTFILE.TXT’ and display the
lines which are not starting with any vowel.
Example:
If the file content is as follows:
An apple a day keeps the doctor away.
We all pray for everyone’s safety.
A marked difference will come in our country.
The COUNTLINES() function should display the output as:
The number of lines not starting with any vowel - 1
def COUNTLINES() :
file = open ('TESTFILE.TXT', 'r')
lines = file.readlines()
count=0
for w in lines :
if (w[0]).lower() not in 'aeoiu'
count = count + 1
print ("The number of lines not starting with any vowel: ", count)
file.close()
COUNTLINES()
2. Write a function ETCount() in Python, which should read each character of a text file “TESTFILE.TXT”
and then count and display the count of occurrence of alphabets E and T individually (including small cases
e and t too).
Ans:
def ETCount() :
file = open ('TESTFILE.TXT', 'r')
lines = file.readlines()
countE=0
countT=0
for w in lines :
for ch in w:
if ch in 'Ee':
countE = countE + 1
if ch in 'Tt':
countT=countT + 1
print ("The number of E or e : ", countE)
print ("The number of T or t : ", countT)
file.close()
, 3. Write a Program in Python that defines and calls the following user defined functions:
a) ADD() – To accept and add data of an employee to a CSV file ‘record.csv’. Each record consists of a list
with field elements as empid, name and mobile to store employee id, employee name and
employee salary respectively.
b) COUNTR() – To count the number of records present in the CSV file named ‘record.csv’.
import csv
def ADD():
fout=open("record.csv","a",newline="\n")
wr=csv.writer(fout)
empid=int(input("Enter Employee id :: "))
name=input("Enter name :: ")
mobile=int(input("Enter mobile number :: "))
lst=[empid,name,mobile]
wr.writerow(lst)
fout.close()
def COUNTR():
fin=open("record.csv","r",newline="\n")
data=csv.reader(fin)
d=list(data)
print(len(d))
fin.close()
ADD()
COUNTR()
4. Write a Program in Python that defines and calls the following user defined functions:
a) add() – To accept and add data of an employee to a CSV file ‘furdata.csv’. Each record consists of a list
with field elements as fid, fname and fprice to store furniture id, furniture name and furniture
price respectively.
b) search()- To display the records of the furniture whose price is more than 10000
import csv
def add():
fout=open("furdata.csv","a",newline='\n')
wr=csv.writer(fout)
fid=int(input("Enter Furniture Id :: "))
fname=input("Enter Furniture name :: ")
fprice=int(input("Enter price :: "))
FD=[fid,fname,fprice]
wr.writerow(FD)
fout.close()
def search():
fin=open("furdata.csv","r",newline='\n')
data=csv.reader(fin)
found=False
print("The Details are")
for i in data:
if int(i[2])>10000:
found=True
print(i[0],i[1],i[2])
lines which are not starting with any vowel.
Example:
If the file content is as follows:
An apple a day keeps the doctor away.
We all pray for everyone’s safety.
A marked difference will come in our country.
The COUNTLINES() function should display the output as:
