1. strings are immutable.
2. any method on string takes a copy of the object.
3.string.upper will convert the string to an upper case
4.string.lower will convert the string to lower case
5. string.rstrip("character") will strip the trailing characters of string
6.string.replace("character/alphabets", new character/alphabets") will replace the existing specified alphabets in string with new ones
7. string.split splits the string at the given alphabet and returns a list of items
8.string.capitalize capitalizes the first character of the word and turns rest all the characters to lower case
9.string.center center aligns the string by adding the number of spaces mentioned in parenthesis
10. string.count counts the total number of a particular set of characters in a string
11. string.endswith checks whether a string ends with the specific characters
12.string.find finds the first occurrence of a given value and return the index value of the position of that occurrence
13.string.index finds the occurrence of a given value and returns the index value of the position however, if it is unable to find it will give an error causing the program to exit
14.string.isalnum checks to find if string is alphanumeric and returns true or false
15.string.isalpha checks if there are any numbers in the string
16.string.islower checks if there are only lower aphabets in the string
17. string.isprintable checks if all the characters are printable in the string(non printable characters e.g \n)
18 string.isspace checks if any space bar has been used in the string
19.string.istitle The istitile() returns True only if the first letter of each word of the string is capitalized, else 20. string.isupper checks if all characters are uppercase in a string
21. string.startswith checks if a string starts with a given value
22. string.swapcase convert uppercase to lowercase and vice versa in a string
23.string.title converts first character of all the words in the sentence to capital

Very best channels for study all programming langauge

Here are few more string methods which may be useful to someone:

1. casefold(): similar to lower() but more aggressive and strong.
2. encode(): return a encoded version of a string.
3. format(): format specific values inside the string.

Note: If you are going though sentences, it counts space too. (for string slicing)

[yashwantsingh]

'rstrip' function strips the character from right side and there is another command 'lstrips' which strips the character from left side and 'strip' function strips the character from anyside of the string

Bro you made things complex as you just printed the length of str1.center(50)
center function centers the string from both ends of the string
For instance:
You should give the example like this:
name = "Harry"
print(name.center(9), end=", ") # you can use any symbol instead of comma

This will be a good and unambiguous example.
This will show that 9-5=4 and 2 spaces will be given to start of the string and 2 at last and at the end of all comma will be printed.

I hope you will consider my suggestion.
I said it because my 2 friends are also watching the playlist and their concept was not cleared about center function.

Man hats off, u r teaching for free and in a good quality too

[T.Akshay_Pratap_Singh]

# converting string into uppercase note: strings are immutable
a = "Harry"
print(len(a))
print(a.upper())
print(a.lower())

# one more example of upper() and lower() functions
str1 = "AbcDEfghIJ"
print(str1.upper())
print(str1.lower())

# using strip() function we can remove white spaces before and after string
str2 = " Silver Spoon "
print(str2.strip())

# rstrip() function used to remove any trailing characters
str3 = "Hello !!!"
print(str3.rstrip("!"))

# replace() method using which we can replace all occurences of string with another string
str2 = "Silver Spoon"
print(str2.replace("Sp", "m"))

# split() method splits the given string at the specified instance and returns the separated strings as list items.
str2 = "Silver Spoon"
print(str2.split(" "))

# capitalize() method is used to turn first character of string into uppercase and rest into lower case
str1 = "hello"
capStr1 = str1.capitalize()
print(capStr1)

str2 = "hello World"
capStr2 = str2.capitalize()
print(capStr2)

# using center() method to align the string to the center
str1 = "Welcome to the Console!!!"
print(str1.center(50))
# another example of center() method
str1 = "Welcome to the Console!!!"
print(str1.center(50, "."))

# count() method returns the number of times the given value has occured within the given string
str2 = "Abracadabra"
countStr = str2.count("a")
print(countStr)

# endswith() method checks if the string ends with a given value. If yes then return True, else return False.
str1 = "Welcome to the Console !!!"
print(str1.endswith("Console !!!"))
# another example of endswith() checking for a value in between the string by providing start and end index positions.
print(str1.endswith("to", 4, 10))

# find() method searches for the first occurrence of the given value and returns the index where it is present. If given value is absent from the string then return -1.
str1 = "He's name is Dan. He is an honest man."
print(str1.find("is"))
print(str1.find("Daniel"))

# index() method searches for the first occurrence of the given value and returns the index where it is present. If given value is absent from the string then raise an exception.
str1 = "He's name is Dan. Dan is an honest man."
print(str1.index("Dan"))
# print(str1.index("Daniel")) # this will show a value error

# isalnum() method returns True only if the entire string only consists of A-Z, a-z, 0-9. If any other characters or punctuations are present, then it returns false.
str1 = "WelcometoTheConsole"
print(str1.isalnum())

# isalpha() method returns True only if the entire string only consists of A-Z, a-z. If any other characters or punctuations or numbers(0-9) are present, then it returns false.
str1 = "Welcome"
print(str1.isalpha())

# islower() method returns True if all the characters in the string are lower case, else it returns false.
str1 = "hello world"
print(str1.islower())

# isprintable() method returns True if all the values within given string are printable, if not, then return False.
str1 = "We wish you a Merry Christmas"
print(str1.isprintable())
str1 = "We wish you a Merry Christmas\n"
print(str1.isprintable()) # this will return False

# isspace() method returns True only and only if the string contains white spaces, else returns False.
str1 = " " # using spacebar
print(str1.isspace())
str2 = " " # using Tab
print(str1.isspace())

# istitle() method returns True only if the first letter of each word of the string is capitalized, else it returns False
str1 = "World Health Organization"
print(str1.istitle())
str2 = "To kill a Mocking bird"
print(str2.istitle())

# isupper() method returns Ture if all the characters in the string are upper case, else it returns False.
str1 = "WORLD HEALTH ORGANIZATION"
print(str1.isupper())

# startswith() method checks if the string starts with a given value. If yes then return True, else return False.
str1 = "Python is a Interpreted Language"


# swapcase() method changes the character casing of the string. Upper case are converted to lower case and lower case to upper case.
str1 = "Python is a Interpreted Language"
print(str1.swapcase())

# title() method capitalizes first letter of each word within the string
str1 = "He's name is Dan. Dan is an honest man"
print(str1.title())

[ratndeepparmar]

Mind blowing explanation of each and every points sir.. Teaching technique is really a best and understandable..

[debasishbesra]

Day3 of #100DaysOfCode. Today in this video13, I learned about various string methods in Python, such as upper(), lower(), strip(), replace(), split(), and many others. These methods will help me manipulate strings effectively, such as changing character casing, aligning text, counting occurrences, and checking specific conditions within strings.
Thank You Harry Bhaiya.
