Example 1: range in while loop python
i = 1
while i in range(0,10):
print("Hello world", i)
i = i + 1
# OUTPUT
Hello world 1
Hello world 2
Hello world 3
Hello world 4
Hello world 5
Hello world 6
Hello world 7
Hello world 8
Hello world 9
print(i)
10
Example 2: python for loop range
for i in range(0, 3):
print(i)
Example 3: python for loop
#to print number from 1 to 10
for i in range(1,11):
print(i)
#to print a list
l = [1,2,3,4]
for i in l:
print(i)
r = ["a","b","c","d","e"]
s = [1,2,3,4,5]
#print two list with the help of zip function
for p,q in zip(r,s):
print(p,q)
Example 4: 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 5: for i in range python
for i in range(start, end):
expression
Example 6: python for loop range
#Python range() example
print("Numbers from range 0 to 6")
for i in range(6):
print(i, end=', ')
