making your own range function in python
def range_by(starting_number, ending_number):
#sequence = [starting_number]
sequence = []
while starting_number < ending_number:
sequence.append(starting_number)
starting_number += 1
return sequence
print(range_by(-3,6))range python 3
# range(start, stop, step)
# start = index to begin at (INCLUSIVE)
# stop = generate numbers up to, but not including this number (EXCLUSIVE)
# step = (can be omitted) difference between each number in the sequence
arr = [19,5,3,22,13]
# range(stop)
for i in range(len(arr)):
print(arr[i]) # prints: 19, 5, 3, 22, 13
# range(start, stop)

print(x)when do we use *range in python
print([*range(20)]) #will give all numbers 1 to 19 in a listCopyright © 2021 Codeinu
