Meta-group
Print ((1+3))

For El in Tu:

The first layer of a tuple cannot be assigned. Internal elements are not required
Tu = (1, "Hello", "How is You?", "aux", ["Geli"])

Print (s)

Range
Range () is an iterative object that can be used for loop
1. Range (n) 0-n-1
For I in range (10):
Print (i)
Range (m, n) #m-n-1
For I in Range (1,10):
Print (i)
3. Range (M,N,Q) m--n-1 each q take one
For I in Range (1,10,3):
Print (i)

For I in range (100, 90,-1):
Print (i)
0 1 2 3 4 5
LST = ["casserole", "Steamed bread", "rice bowls", "knife noodles", "Big Twist", "Big Pancake"]
Gets the index to the list. After getting the index. can get the element
For I in range (len (LST)):
Print (i) # I is the index of the LST
Print (Lst[i])
For El in LST: # (el = element, meaning that each element in the output list is iterated)
Print (EL)
