print(name[0])
print(name[-1])

port = 2020
print(str(port)[-1])

## Slice operation

timestamp = "19-07-2023"

## Buil in functions

### lowerfn()

name = "PrinCE"
print("The name", name , "is converted to lower :", name.lower())

### upper

name = "prince"
print("The name", name , "is converted to upper :", name.upper())

### isdigit()

s1 = "abc"
s2 = "abc123"
s3 = "123"

print(s1, s1.isdigit())
print(s2, s2.isdigit())
print(s3,s3.isdigit())

num = input("Enter the digit to check whether it's odd or even : ")
if num.isdigit():
  if int(num) % 2 == 0:
    print("The number is even")
  else:
    print("The number is odd")
else:
  print("Sorry invalid digit")

### isalpha

s1 = "abc123"
s2 = "123"
s3 = "abc"

print(s1, s1.isalpha())
print(s2,s2.isalpha())
print(s3,s3.isalpha())

word = input("Enter the word to check : ")
if word.isalpha():
  print("The word you entered is an alphabet")
if word.isdigit():
  print("The input you entered is a digit")

word = input("Enter a character : ")
if len(word) == 1:
  if word.isalpha():
    print("Your input is an alphabet")
  if word.isdigit():
    print("Your input is a digit")
else:
  print("Please enter one char only....try again, Thank you!")

### replace

word = "malayalam"
new = word.replace("a","A")
print(word, "is now converted to upper A", new)

new = word.replace("a"," ")
print(new)


new = word.replace("a","")
print(new)

### count

word = "Malayalam"
new = word.count("a")
new1 = word.count("l")
new2 = word.count("m")

print(new , new1, new2)

word = "malayaLAm"
x = 0
y = 0
for item in word:
  if item == "a":
    x = x + 1
  if item == "A":
    y = y + 1
print("The number of a in the word", word , x)
print("The number of A in the word", word , y)


### Starts and endswith

conf = "/etc/httpf/conf/httpd.conf"
result = conf.startswith("/")
print(result)


result = conf.startswith("/etc")
print(result)

result = conf.startswith("etc")
print(result)

result = conf.endswith(".conf")
print(result)

result = conf.endswith("httpd.conf")
print(result)

result = conf.endswith(".cfg")
print(result)

### is upper and is lower

s1 = "a"
s2 = "AA"
s3 = "ABCabc"
s4 = "a12"
s5 = "A"

print(s1, s1.isupper())
print(s1,s1.islower())

print(s2,s2.isupper())
print(s2, s2.islower())

print(s3,s3.isupper())
print(s3, s3.islower())

print(s4,s4.isupper())
print(s4, s4.islower())

print(s5,s5.isupper())
print(s5, s5.islower())

##------------------------------------------ Task 2 -----------------------------------------------##

## 1] Replace character with 23-12-2022 to 23/12/2022

word = "23-12-2022"
new = word.replace("-","/")
print(new)

Ans] 23/12/2022

### 2] Find the n.o of occurence of the char "a" or "A "

word = "MAlayaLAm"
x = 0
y = 0
for item in word:
  if item == "a":
    x = x + 1
  if item == "A":
    y = y + 1
print("The number of a in the word", word,"is : ", x)
print("The number of A in the word", word,"is : ", y)

Ans]
The number of a in the word MAlayaLAm is :  2
The number of A in the word MAlayaLAm is :  2


### 3] Print the total n.o of digits.

word = "a1b2c3D4E4F5"
x = 0
for item in word:
  if item.isdigit():
    x = x + 1
print("The total n.o of digits in the word", word, "is: ", x)

Ans] The total n.o of digits in the word a1b2c3D4E4F5 is:  6


### 4] Print the total n.o of small letters

word = "a1b2c3D4E4F5"
x = 0
for item in word:
  if item.islower():
    x = x + 1
print("The total n.o of small letters in the word", word,"is: ", x )

Ans] The total n.o of small letters in the word a1b2c3D4E4F5 is:  3


### 5] Print the total n.o of Capital letters

word = "a1b2c3D4E4F5"
x = 0
for item in word:
  if item.isupper():
    x = x + 1
print("The total n.o of Capital letters in the word", word,"is: ", x )

Ans] The total n.o of Capital letters in the word a1b2c3D4E4F5 is:  3


### 6] Find the number of spaces

sentence = "This post is to illustrate how to access the docker container network namespace"
x = 0
for item in sentence:
  if item == " ":
    x = x + 1
print("the number of spaces is: ",x)

Ans] the number of spaces is:  12

### 7] Fix the error

#### Corrected code

number = input("enter a number ")
if number.isdigit():
  if int(number) % 2 == 0:
    print("even")
  else:
    print("odd")
else:
  print("Sorry you've entered a wrong input")
