String Methods in Python

len():

len() is used to find the length of a string.

Sample Code:

strInfo = input( 
    'Enter a String: '
);
print(
    'Length of ' +
    strInfo + 
    ' is',
    len( strInfo )
);

Slicing String:

We can slice the string using the start and end indexes.

Sample Code:

strInfo = input( 
    'Enter a String: '
);
strStart = input( 
    'Enter Start Index: '
);
strEnd = input( 
    'Enter End Index: '
);
intStart = int( strStart );
intEnd = int ( strEnd );
print(
    strInfo[ intStart : intEnd ]
);

lower():

lower() is used to convert it to lowercase.

Sample Code:

strInfo = input( 
    'Enter a String in Uppercase: '
);
print(
    'Lowercase is',
    strInfo.lower()
);

upper():

upper() is used to convert the string to uppercase.

Sample Code:

strInfo = input( 
    'Enter a String in Lowercase: '
);
print(
    'Uppercase is',
    strInfo.upper()
);

replace():

replace() is used to replace search string with replacement string.

Sample Code:

strInfo = 'Testing Python';
print(
    'Testing replaced with Test is',
    strInfo.replace( 'Testing', 'Test' )
);

lstrip():

Removes whitespace on the left/beginning.

rstrip():

Removes whitespace on the right/ending.

Removes whitespaces in the beginning and ending.

startswith():

Returns a boolean value whether the string starts with the specified string.

find():

Returns the position of specified String.

Sample Code:

strInfo = 'test # example';
print(
    'Position of # is',
    strInfo.find( '#' )
);
