Create a function joinStrings(str1, str2) that takes two different strings as parameters, str1 and str2, and returns them as one string with str1 before str2. For example, joinStrings('he','llo') returns hello.

        def joinStrings(str1, str2):
---
def joinStrings(): #paired
---
    joined = str1 + str2
---
    joined = str1.join(str2) #paired
---
    return joined
---
    Return joined #paired

Write a function joinStrings(str1, str2) that takes two different strings as parameters, str1 and str2, and returns them as one string with str1 before str2. For example, joinStrings('he','llo') returns hello.

Create a function rect_per(w, h) that takes the width, w, and the height, h, as parameters. Calculate the perimeter, which is the width plus the height times two, and return a string in the form - Perimeter of rectangle with width of (w) and height of (h) is (perimeter). For example, rect_per(5,10) returns Perimeter of rectangle with width of 5 and height of 10 is 30.

        def rect_per(w, h):
---
def rect_per(w, h) #paired
---
    perimeter = (w + h) * 2
---
    perimeter = w + h * 2 #paired
---
    answer = "Perimeter of rectangle with width of " + str(w) + " and height of " + str(h) + " is " + str(perimeter)
---
    answer = "Perimeter of rectangle with width of " + str(w) + " and height of " + str(h) + " is " + perimeter #paired
---
    return answer

Create a function cube(n) that takes a number, n, and cubes it and returns a string in the form Cube of (n) is (n cubed). For example, cube(4) returns Cube of 4 is 64.

        def cube(n):
---
    cube_num = n ** 3
---
    cube_num = n * 3 #paired
---
    answer = "Cube of " + str(n) + " is " + str(cube_num)
---
    return answer
---
    return cube_num #paired

Write a function cube(n) that takes a number, n, and cubes it and returns a string in the form Cube of (n) is (n cubed). For example, cube(4) returns Cube of 4 is 64.

Create a function atlas(c_name) that takes a country name, c_name, as a parameter and returns a string in the form of The last letter of (c_name) is (last). For example, atlas('Germany') returns The last letter of Germany is y.

        def atlas(c_name):
---
    last = c_name[-1]
---
    last = c_name[:-1] #paired
---
    return("The last letter of " + c_name + " is " + last)
---
    return("The last letter of" + c_name + "is" + last) #paired

Write a function atlas(c_name) that takes a country name, c_name, as a parameter and returns a string in the form of The last letter of (c_name) is (last). For example, atlas('Germany') returns The last letter of Germany is y.

Create a function dateYear(date) that takes a string, date, in the format MM/DD/YYYY and returns the year. For example, dateYear(11/07/2000) should return 2000.

        def dateYear(date):
---
    year = date[6:]
---
    year = date[7:] #paired
---
    return year

Write a function dateYear(date) that takes a string, date, in the format MM/DD/YYYY and returns the year. For example, dateYear(11/07/2000) should return 2000.

Create a function capitalize(str), that takes a string, str, and returns the string with the first letter capitalized. For example, capitalize('america') would return America.

        def capitalize(str):
---
Def Capitalize(str): #paired
---
    answer = str[0].upper() + str[1:]
---
    answer = str.upper() + str[1:] #paired
---
    return answer

Write a function capitalize(str), that takes a string, str, and returns the string with the first letter capitalized. For example, capitalize('america') would return America.

Create a function mod_password(password), that takes a string, password, and returns a new string that replaces all 's' in the string with '$'. For example, mod_password('suspense') returns $u$pen$e.

        def mod_password(password):
---
    new = password.replace('s', '$')
---
    new = password.remove('s') + '$' #paired
---
    return new

Create a function first_last(str), that takes a string, str, and returns a new string with the first two characters of the word followed by the last two characters. Assume str is four characters or more. For example, first_last('wander') returns waer.

        def first_last(str):
---
    out = str[:2] + str[-2:]
---
    out = str[-2:] + str[:2] #paired
---
    return out
