range parameters in python code example

Example 1: for in range loop python

#there are two possibilities for a for loop
#first one is with a range()
#range() just generates lists after the following pattern

print(range(4))
>>> [0,1,2,3]
print(range(1,4))
>>> [1,2,3]
print(range(2,10,2))
>>> [2,4,6,8]

#and what the for does then is that it lets a variable (in my example x) cycle trough the list given after in

for x in range(2,10,2):
  print(x)
>>> 2
>>> 4
>>> 6
>>> 8

#so the code in the loop gets executed for every value in the given list after in
#you can also use for ... in for custom lists
#example 1:

list1 = [1,2,50,2]

for x in list1:
  print(x)

>>> 1
>>> 2
>>> 50
>>> 2

#example 2

list2 = ["bananas", "apples", "pears"]

for x in list2:
  print(x)

>>> "bananas"
>>> "apples"
>>> "pears"

Example 2: python range in intervals of 10

print("using start, stop, and step arguments in Python range() function")
print("Printing All odd numbers between 1 and 10 using range()")
for i in range(1, 10, 2):
    print(i, end=', ')

Example 3: range in python

#range(start,stop,step)
for x in range(0,20,2):
  print(x)

Example 4: class range python code

class Range:
   def __init__(self, start, end):
      self.setStart(start)
      self.setEnd(end)
   def getStart(self):
      return self.start
   def setStart(self, s):
      self.start = s
   def getEnd(self):
      return self.end
   def setEnd(self, e):
      self.end = e
   def getLength(self):
      return len(range(self.start, self.end))
   def overlaps(self, r):
      if (r.getStart() < self.getEnd() and r.getEnd() >= self.getEnd()) or \
         (self.getStart() < r.getEnd() and self.getEnd() >= r.getEnd()) or \
         (self.getStart() >= r.getStart() and self.getEnd() <= r.getEnd()) or \
         (r.getStart() >= self.getStart() and r.getEnd() <= self.getEnd()):
          return True
      else:
          return False
