測試題
1. 使用 def 關鍵字來創建一個函數。
2. 調用函數時要使用函數名和一對小括號。
3. 調用函數時把參數放在小括號裡，就可以向這個函數傳入參數。
4. 一個函數可以有任意多個參數，對此沒有任何限制。
5. 函數使用 return 關鍵字向調用者發回信息。
6. 函數完成運行後，所有局部變量都會撤銷。
動手試一試
1. 這個函數只需要一組 print 語句：
def printMyNameBig: print " CCCC A RRRRR TTTTTTT EEEEEE RRRRR " print " C C A A R R T E R R " print "C A A R R T EEEE R R " print "C AAAAAAA RRRRR T E RRRRR " print " C C A A R R T E R R " print " CCCC A A R R T EEEEEE R R" 調用這個函數的程序如下所示：
for i in range(5): printMyNameBig 2. 下面給出我的做法，這裡利用 7 個參數打印地址：
# define a function with seven argumentsdef printAddr(name, num, street, city, prov, pcode, country): print name print num, print street print city, if prov !="":print ", "+prov else:print "" print pcode print country print#call the function and pass seven arguments to itprintAddr("Sam", "45", "Main St.", "Ottawa", "ON", "K2M 2E9", "Canada")printAddr("Jian", "64", "2nd Ave.", "Hong Kong", "", "235643", "China") 3. 沒有具體答案，可以動手試一試。
4. 合計零錢的函數應當如下所示：
def addUpChange(quarters, dimes, nickels, pennies): total = 0.25 * quarters + 0.10 * dimes + 0.05 * nickels + 0.01 *pennies return total 調用它的程序可能如下所示：
quarters = int(raw_input("quarters: "))dimes = int(raw_input("dimes: "))nickels = int(raw_input("nickels: "))pennies = int(raw_input("pennies: "))total = addUpChange(quarters, dimes, nickels, pennies)print "You have a total of: ", total
