for in range in python code example

Example 1: python for loop range

for i in range(0, 3):
    print(i)

Example 2: 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 3: for i in range python

for i in range(start, end):
  expression

Example 4: range(n,n) python

# if numbers are same in the range function then,
# the range function outputs empty range
# this is because, there are no integers b/w n and n
for i in range(1,1):
  print("runs")

# prints nothing

Example 5: for i in range python

times_repeated = 10

for i in range(1, times_repeated + 1): #1 is the starting point and times_repeated is how much times the loop with run.
  print(i) #Prints 1 2 3 4 ... 10
