More than one conditional statement
You can put multiple conditions together in that statement.
Lets consider a situation where we want to go through all the numbers in a list and sum all the values that are between 4 and 7. For example is our list is: lst = [1,5,4,12,18,6] our result would be 5+4+6 = 15
Steps to a solution:
- Create sum = 0
- Iterate through list of numbers
- If the number > 3 and number < 7, add it to the sum
Solution:
lst = [1,5,4,12,18,6]
#Initialize the sum
s = 0
#Iterate through all the numbers in the list
for number in lst:
#if the number meets our condition, add it to the sum
if (number > 3) and (number < 7):
s += number
# Print out the sum after the loop
print(s)
Or Statements
As well, instead of using and, we can use the or statement. Lets say you have a list of words, and you only want to print out the word if it is more than 5 characters long or it contains the letter s.
For example, if our list was: lst = ['hello', 'world', 'I', 'really','like','cats']
we would want to print out:
really
cats
To do this we would implement the following code:
lst = ['hello', 'world', 'I', 'really','like','cats']
# Iterate through all the words
for word in lst:
# Add our condition (more than 3 letters or contains 's')
if (len(word) > 5) or ('s' in word ):
# If it met our condition, print the wordexit
print(word)
