1. The differences between common parameters, specified parameters, default parameters and dynamic parameters are briefly described.

2, write function, calculate the number of "number", "Letter", "space" and "other" in the incoming string

def My_len (my_def):2      my_def.split ()3      return  len (my_def)4 res = My_len (  'hfweiie8832  fej Chinese ')print(res)

3, write function, to determine whether the user incoming objects (string, list, tuple) length is greater than 5.

1 defMy_fun (func):2My_count =03      forIinchfunc:4My_count = My_count + 15     ifMy_count > 5:6         Print('The length of the object you passed in is greater than 5')7     Else:8         Print('The length of the object you passed in is not greater than 5')9 TenMy_fun ([1, 2,'JDI','English'])

4. Write function to check whether each element of the user's incoming object (string, list, tuple) contains empty content.

1 defMy_fun (func):2      forIinchfunc:3         ifi.isspace ():4              Print('This element contains empty content')5         Else:6             Continue7 8My_fun ([' ',' A','3','4','DIW'])

5, write the function, check the length of the incoming list, if greater than 2, then only the first two length of the content, and return the new content to the caller.

1 defMy_fun (func):2My_count =03      forIinchfunc:4My_count = My_count + 15     ifMy_count > 2:6Func = Func[0:2]7         returnfunc8res = My_fun ([A.'Edj'])9 Print(RES)

6. Write the function, check the element that gets all the odd bit indexes of the incoming list or tuple object, and return it to the caller as a new list.

1 defMy_fun (func):2My_count =03Func1 = []4      forIinchfunc:5My_count = My_count + 16         ifMy_count% 2 = =0:7 func1.append (i)8     Print(FUNC1)9My_fun ([A.'Edj'])

7, write the function, check the length of each value passed into the dictionary, if greater than 2, then only the first two length of the content, and the new content is returned to the caller.

1 defmy_dict (DIC):2      forKeyinchDIC:3         ifLen (Dic[key]) > 2:4Dic[key] = Dic[key][0:2]5         Else:6             Continue7     returnDiC8DIC = {"K1":"v1v1","K2": [11,22,33,44]}9res =my_dict (DIC)Ten Print(RES)

8, write the function, use recursion to get the 10th number in the Fibonacci sequence, and return the value to the caller.

1 defMy_feb (n):2My_count =03Arg1 = 14ARG2 = 15      forKinchRange (1, (n+1)):6         ifMy_count < n andMy_count >= 2:7My_count = My_count + 18Arg3 = Arg1 +arg29Arg1 =arg2TenArg2 =Arg3 One         Else: AMy_count = My_count + 1 -Arg3 = 1 -     returnArg3 theres = My_feb (10) - Print(RES)
