#While Loop:
while ("condition that if true the loop continues"):
#Do whatever you want here
else: #If the while loop reaches the end do the things inside here
#Do whatever you want here
#For Loop:
for x in range("how many times you want to run"):
#Do whatever you want herepython for loop
# A for loop in python is used to iterate (or loop) over a sequence.
# The sequence is usually range(start,end), but can also be a list.
# Example of for loop with range():
for num in range(1,10):
print(num)
# This prints all the numbers from 1 to 10, including 1 but excluding 10.
# Here is an example of a for loop with a list:
lst = [1,2,3,4,5]
for item in lst:
print(item)
# This prints all items in the list.
# For loops are also used in list comprehensions.
lst = [1,2,3,4,5]
new_lst = [item for item in lst if i % 2 == 0]
# The list comprehension above generates a new list, which new_lst is put equal to.
# It iterates through the items in lst and only puts them in the new list if it is a multiple of 2.python for loop
# Python for loop
for i in range(1, 101):
# i is automatically equals to 0 if has no mention before
# range(1, 101) is making the loop 100 times (range(1, 151) will make it to loop 150 times)
print(i) # prints the number of i (equals to the loop number)
for x in [1, 2, 3, 4, 5]:
# it will loop the length of the list (in that case 5 times)
print(x) # prints the item in the index of the list that the loop is currently onpython for loop
# Range:
for x in range(5):
print(x) # prints 0,1,2,3,4
# Lists:
letters = ['a', 'b', 'c']
for letter in letters:
print(letter) # prints a, b, c
# Dictionaries:
letters = {'a': 1, 'b': 2, 'c': 3}
for letter, num in letters.items():
print(letter, num) # prints a 1, b 2, c 3Copyright © 2021 Codeinu
