Strings are text type and are sequences of character data. It is represented by quotation marks, either single or double quotes.<\/p>\n

Example:<\/p>\n

“Hello”<\/p>\n

‘What is your name?’<\/p>\n

>>> “Hello”
\n‘Hello’
\n>>> x = ‘What is your name?’
\n>>> print (x)
\nWhat is your name?
\n>>><\/p><\/blockquote>\n

Some key notes:<\/p>\n

1.Escape sequences in strings = use backslash (\\) character<\/p>\n

Examples:<\/div>\n

 <\/p>\n

\n
>>> print (‘This is a single quote symbol \\’ ‘)<\/div>\n<\/blockquote>\n
\n
\n
This is a single quote symbol ‘<\/div>\n
>>> print (‘This is a single quote symbol (\\’)’)<\/div>\n
This is a single quote symbol (‘)<\/div>\n
>>> print (“This is a single quote symbol (\\’)”)<\/div>\n
This is a single quote symbol (‘)<\/div>\n<\/blockquote>\n<\/div>\n
<\/div>\n
\n
\n
>>> print (‘I’m handsome’)<\/div>\n
\u00a0 File “<stdin>”, line 1<\/div>\n
\u00a0 \u00a0 print (‘I’m handsome’)<\/div>\n
\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 ^<\/div>\n
SyntaxError: invalid syntax<\/div>\n
>>> print (‘I\\’m handsome’)<\/div>\n
I’m handsome<\/div>\n<\/blockquote>\n<\/div>\n
\n
<\/div>\n
\n
>>> x = “I am the \\”King\\” of this land”<\/div>\n
>>> print (x)<\/div>\n
I am the “King” of this land<\/div>\n<\/div>\n
<\/div>\n<\/blockquote>\n
\n
\n
>>> print (‘This is a backslash symbol \\\\’)<\/div>\n
This is a backslash symbol \\<\/div>\n<\/blockquote>\n<\/div>\n
<\/div>\n
Other popular escape characters:
\n\\n = new line<\/div>\n
\\t = tab<\/div>\n
<\/div>\n
\n
\n
>>> print (‘test \\n only’)<\/div>\n
test<\/div>\n
\u00a0only<\/div>\n<\/blockquote>\n<\/div>\n
\n
\n
>>> print (‘test \\t only’)<\/div>\n
test\u00a0 \u00a0 \u00a0only<\/div>\n<\/blockquote>\n<\/div>\n
\n
<\/div>\n<\/blockquote>\n

2. Since it is a sequence, can use indexing and slicing for the subsets of strings using the slice operator\u00a0\u00a0([ ] and [:] ). Indexes starting “0” in the start of the string.<\/p>\n

<\/div>\n
Example:<\/div>\n
Character: E\u00a0 u\u00a0 a\u00a0 n<\/div>\n
Index:\u00a0 \u00a0 \u00a0 \u00a0 0\u00a0 1\u00a0 2\u00a0 3<\/div>\n
Neg Index:-4 -3 -2 -1<\/div>\n
\n
<\/div>\n
>>> x = “Euan”
\n>>> print(x[0])
\nE
\n>>> print(x[3])
\nn
\n>>> print(x[-3])
\nu
\n>>> print(x[-4])
\nE<\/div>\n<\/blockquote>\n
For slicing, it lets you access parts of the sequence, normally we use it if we want to get the part of the string and not the complete string.<\/div>\n
Syntax:<\/div>\n
string[start : end : step]<\/div>\n
where:<\/div>\n
start = starting index<\/div>\n
end = end index (not included in substring,go up to but don’t include it<\/span>)<\/div>\n
step=optional argument determining the increment between each index for slicing<\/div>\n
Example:<\/div>\n
W r\u00a0 i\u00a0 t\u00a0 e c o d e<\/div>\n
\u00a00 1 2 3 4\u00a0 5 6 7 8<\/div>\n
<\/div>\n
You only want to get the word code in this string (remember the indexing concept<\/div>\n

>>> x =”Writecode”
\n>>> print(x)
\nWritecode
\n>>> print (x[5:])
\ncode<\/p><\/blockquote>\n

<\/div>\n
So if you want to get the word “Write”, then you can do this way<\/div>\n
<\/div>\n
\n
>>> print (x[:5])
\nWrite<\/div>\n<\/blockquote>\n
<\/div>\n
How about middle?example we want to take word “teco”<\/div>\n
<\/div>\n
\n
>>> print (x[3:7])
\nteco<\/div>\n<\/blockquote>\n
<\/div>\n
