How to use for loop in Python
Python For Loops
A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.
Python Features Highlights
- Python-For Loops
- Looping Through a String
- The break Statement
The for loop we can execute a set of statements, once for each item in a list, tuple, set etc. Also check How to Find the Square Root using Python Program
Example
Print each city in a city list:city = ["salem", "chennai", "Bangalore"]for x in city:print(x)
Looping Through a String
Even strings are iterable objects, they contain a sequence of characters:
Example
Loop through the letters in the word "chennai":
for x in "chennai":
print(x)
The break Statement
With the break statement we can stop the loop before it has looped through all the items:
Example
Exit the loop when x is "chennai":
city = ["salem", "chennai", "Bangalore"]
for x in city:
print(x)
if x == "chennai":
break
