initialization : variable is initialized and sets the initial value Condition: Python condition that evaluates true and false. It is used to test whether the loop continues or exits. increment/decrement: updated variable value by add/subtract Syntax: for( initialization; condition;increment/decrement){ //code statements body } ... s = 'hello' for c in s: print(c) Looping through a dictionary: Copy code # Print the keys and values of a dictionary emps = {'john': 1, 'eric': 2, 'mark': 3} for name, id in emps.items(): print(f'{name}: {id}') Looping with a counter: # Print the numbers 0 to 9, along with their indices numbers = ['one', 'two', 'three'] for i, number in enumerate(numbers): print(f'{i}: {number}') These are just a few examples of the types of for loops you can use in Python.

If a break statement is executed inside the for loop then the "else" part is skipped. Note that the "else" part is executed even if there is a continue statement. ... # Prints out 0,1,2,3,4 and then it prints "count value reached 5" count=0 while(count<5): print(count) count +=1 else: print("count value reached %d" %(count)) # Prints out 1,2,3,4 for i in range(1, 10): if(i%5==0): break print(i) else: print("this is not printed because for loop is terminated because of break but not due to fail in condition")
