Prerequisite – Strings in Python
Predict the output of the following Python programs. These question set will make you conversant with String Concepts in Python programming language.
- Program 1
# statement 1
# statement 2chevron_right
var1: H var2[1:5]: eeks
Strings are among the most popular types in Python. We can create a string by enclosing characters within quotes. Python treats single quotes same as double quotes. It is notable that unlike C or C++ python does not support a character type; in fact single characters are treated as strings of length one, thus also considered a substring. To access substrings, use the square brackets for slicing along with the index or indices to obtain your substring.
Statement 1: will simply put character at 0 index on the output screen.
Statement 2: will put the character starting from 0 index to index 4.
- Program 2
"Orignal String :-"
"Updated String :- "
# statement 1chevron_right
Orignal String :- Geeks Updated String :- GeeksforGeeks
Python provides a flexible way to update string in your code. Use square brackets and specify the index from where string has to be updated and use + operator to append the string. [x:y] operator is called Range Slice and gives the characters from the given range.
Statement 1: In the given code tells the interpreter that from 5th index of string present in var1 append ‘for’ and ‘Geeks’ to it.
- Program 3
"""this is a long string that is made up of
several lines and non-printable characters such as
TAB ( \t ) and they will show up that way when displayed.
NEWLINEs within the string, whether explicitly given like
this within the brackets [ \n ], or just a NEWLINE within
the variable assignment will also show up.
this is a long string that is made up of several lines and non-printable characters such as TAB ( ) and they will show up that way when displayed. NEWLINEs within the string, whether explicitly given like this within the brackets [ ], or just a NEWLINE within the variable assignment will also show up.
Python’s triple quotes comes to the rescue by allowing strings to span multiple lines, including NEWLINEs, TABs, and any other special characters.The syntax for triple quotes consists of three consecutive single or double quotes.
- Program 4
'C:\\inside C directory'
'C:\\inside C directory'
C:\inside C directory C:\\inside C directory
Raw strings do not treat the backslash as special characters at all.
Statement 1 : will print the message while considering backslash as a special character.
Statement 2 : is a raw string that will treat backslash as a normal character.
- Program 5
In the above code \x is an escape sequence that means the following 2 digits are a hexadecimal number encoding a character. Hence the corresponding symbols will be on the output screen.
