range() python code example

Example 1: for i in range start

for i in range([start], stop[, step])

Example 2: 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)
for i in range(2, len(arr)):
    print(arr[i]) # prints: 3, 22, 13
    
# range(start, stop, step)
for i in range(0, len(arr), 2):
    print(arr[i]) # prints: 19, 3, 13
    
# reverse:
for i in range(len(arr)-1, -1, -1):
    print(arr[i])

Example 3: range between things py

num1= = 100
num2 = 904574
range_between_num1_and_num2 = num2 - num1

Example 4: python range

# range(start, stop, step)
  # start = (can be ommitted) 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

# idx:  0	1	2	3 	4
# arr:  19	5	3	22	13
  
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)
for i in range(2, len(arr)):
    print(arr[i]) # prints: 3, 22, 13
    
# range(start, stop, step)
for i in range(0, len(arr), 2):
    print(arr[i]) # prints: 19, 3, 13
    
# reverse:
for i in range(len(arr)-1, -1, -1):
    print(arr[i])

Example 5: for i in range python

for i in range(start, end):
  expression

Example 6: range() python

#can be used a sequence of numbers
x = range(6)
print(x)
#Outputs 0 1 2 3 4 5

for i in range(start,finish ,step) 
#gives range of numbers
#start is optional default is 0
#finish needed specifying when to stop
#step is incremetntaition of jump also optional
