### Function

 print() Show inform­ation that you want on the screen int() Change number to be number integer float() Change number to be decimal number input() Gain inform­ation from user str() A list of number, letter and symbols len() The length of the string # Comment, no effect

 string + string Combine together string + number CRASH! number + number Addition (Math)

### Function- maxvalue

 ``````# name: max2 # arguments: num1, num2 # return: the largest value def max2(num1, num2):     maxvalue = num1     if num2 > num1:         maxvalue = num2     return maxvalue print(max2(10, 9)) print(max2(1, 9)) # write a function that returns the largest of three values # name: max3 # arguments: num1, num2, num3 # return: the largest value def max3(num1, num2, num3):     maxvalue = num1     if num2 > maxvalue:         maxvalue = num2     if num3 > maxvalue:         maxvalue = num3     return maxvalue print(max3(2, 12, 4)) print(max3(19, 9, 17)) # write a function that returns the largest number in a list # name: maxlist # arguments: list # return the largest value in the list def maxlist(list):     # loop through the list     return maxvalue numlist = (1, 2, 3, 4, 5, 99) print(maxlist(numlist))``````

### Math

 == equal to != no equal to < less than > more than <= less than or equal to >= more than or equal to % Modulo, Find the remainder

### Reverse Word

 while True: word = input(­­"­P­lease enter a word") index = 0 reverse = ' ' while int(index) < len(word): reverse = word[i­­ndex] + (reverse) index = int(index) + 1 print ("Re­­verse: ", reverse)

### Convert to binary

 Convert to binary user_n­­umber = ' ' while user_n­­umber != ' 0 ' : user_n­­umber = input ("Enter a number to convert to binary­­") number = int(us­­er­_­n­umber) binary­­_s­tring = ' ' while (number > 0): remainder = number%2 binary­­_s­tring = str(re­­ma­i­n­der)+ binary­­_s­tring number = number//2 print ("Binary string is", binary­­_s­t­ring)
