the miracle lies in line 4 for b[n] in a it means: iterate a and in each iteration assign the actual value to b[n] n is increased by one each time a : b c d n: 1 2 3 b[1] = b b[2]=c b[3] =d

Such and similar tasks appear occasionally. > I don't think codes like this have any practical relevance. they only serve to cause confusion in questions, interviews or challenges.

first time I saw it used like this. Very interesting. usually, I would do a=['b','c','d'] b={1:'a'} for n,v in enumerate(a): b[n+1] = v print(b) "for b[n] in a" is really unusual. Feels like a cross between a regular conditional and list comprehension 😁

Python's list, tuple and dictionary comprehensions are commonly used with range, enumerate, zip to create new objects.

Lothar , you may be right, but still it is necessary to understand this type of codes as it will be useful when you reach upper level at software developer

This code is binding value of dictionary to values of list. Please tell if there are more ways to bind value of one type to other. (Like list to dict, in this case) Thanks

Boolean Logic Given the age of a person as an input, output their age group. Here are the age groups you need to handle: Child: 0 to 11 Teen: 12 to 17 Adult: 18 to 64 Sample Input 42 Sample Output Adult age=int(input ()) If age>0 and age<=11: Print("Child ") elif age>=12 and age<=17: Print("Teen") elif age>=18 and <=64: Print("Adult") This programme is not run. Where is error ....
