Explain the syntax of for loop and the utility of range() with examples
The syntax of a for loop in Python is 'for item in iterable:'. The 'item' represents the current element in the iteration, and 'iterable' is a collection of elements. The range() function is used to generate a sequence of numbers, and it is commonly used with for loops for iterating a specific number of times. Example: for i in range(5): print(i) will output 0, 1, 2, 3, 4.

Study Notes
For Loop Syntax in Python
- The syntax of a for loop in Python is:
for variable in iterable: -
variableis the name given to the variable that takes on the value of each item in theiterableduring each iteration -
iterableis a sequence (such as a string, tuple, or list) or other iterable object
Utility of the range() Function
- The
range()function generates a sequence of numbers starting from the first argument, and stopping before the second argument - It is often used to create a loop that repeats a certain number of times
- The
range()function is commonly used with a for loop to iterate over a sequence of numbers
Using range() with a For Loop
- Example:
for i in range(1, 6): print(i)will output the numbers 1 through 5 - This is equivalent to a loop that runs 5 times, with the variable
itaking on the values 1, 2, 3, 4, and 5 in succession - The
range()function can also be used with a single argument, which specifies the stopping point, and the starting point is assumed to be 0 - Example:
for i in range(5): print(i)will output the numbers 0 through 4
