• Python3
for letter in ‘geeksforgeeks’:

# break the loop as soon it sees ‘e’
# or ‘s’
if letter == ‘e’ or letter == ‘s’:

break
print(‘Current Letter :’, letter)
Output:

Current Letter : e
Python Pass
We use pass statements to write empty loops. Pass is also used for empty control statements, functions, and
classes.

# An empty loop

Python String
Till now, we have discussed numbers as the standard data-types in Python. In this section of the tutorial, we will
discuss the most popular data type in Python, i.e., string.
Python string is the collection of the characters surrounded by single quotes, double quotes, or triple quotes. The
computer does not understand the characters; internally, it stores manipulated character as the combination of
the 0’s and 1’s.
Each character is encoded in the ASCII or Unicode character. So we can say that Python strings are also called
the collection of Unicode characters.
In Python, strings can be created by enclosing the character or the sequence of characters in the quotes. Python
allows us to use single quotes, double quotes, or triple quotes to create the string.
Consider the following example in Python to create a string.
Syntax:
1 str = “Hi Python !”
Here, if we check the type of the variable str using a Python script

1 print(type(str)), then it will print a string (str).
In Python, strings are treated as the sequence of characters, which means that Python doesn’t support the
character data-type; instead, a single character written as ‘p’ is treated as the string of length 1.
Creating String in Python
We can create a string by enclosing the characters in single-quotes or double- quotes. Python also provides triple-
quotes to represent the string, but it is generally used for multiline string or docstrings.
