This article is to share with you about the basic operation of python sequence. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Create sequence syntax:

Variable name = {}

Dict= {}

Variable name = []

List01= []

Variable name = () immutable

Tuple01= ()

Variable name = value

Str='123'

Note: except Yuanzu, all the sequences can have the function of adding, deleting, modifying and searching.

# add dictionaries

Stu_info= {'num':'001','name':' Yuan Tiangang', 'sex':' male'}

Stu_info ['age'] =' 78'

Print (stu_info)

# list

List01= ['002' Li Chunfeng', 'male']

List01.append (64)

Print (list01)

# string

Str01='003\ t Wu Zetian\ t female'

Str01='003\ t Wu Zetian\ t female\ t59'

Print (str01)

# Delete

# Dictionary

Stu_info= {'num':'001','name':' Yuan Tiangang', 'sex':' male'}

Del stu_info ['sex']

Print (stu_info)

# list

List01= ['002' Li Chunfeng', 'male']

Del list01 [2]

Print (list01)

# string

Str01='003\ t Wu Zetian\ t female'

Str01='003\ t Wu Zetian'

Print (str01)

# change

# Dictionary

Stu_info= {'num':'001','name':' Yuan Tiangang', 'sex':' male'}

Stu_info.update ({'sex':' female'})

Print (stu_info)

# list

List01= ['002' Li Chunfeng', 'male']

List01 [2] = 'unknown'

Print (list01)

# string

Str01='003\ t Wu Zetian\ t female'

Str01='003\ t Wu Zetian\ t male'

Print (str01)

Comprehensive case demonstration: making student information management system

Nameinfo= []

Def printMemu ():

Print ("20")

Print ("= = Student Management system V1.0 students =")

Print ("20")

Print ("1: add student information")

Print ("2: delete student information")

Print ("3: show student information")

Print ("4: exit the system")

Def add ():

Num=input ("Please enter student ID:")

Nmae=input ("Please enter student name:")

Sex=input ("Please enter student gender (male / female)")

NewInfo= {}

NewInfo ['num'] = num

NewInfo ['name'] = nmae

NewInfo ['sex'] = sex

Nameinfo.append (newInfo)

Print (nameinfo)

Def show ():

Print ("20")

Print ("Student information is as follows:")

Print ("20")

Print (nameinfo)

Def delete ():

Del_num=input ("Please enter the student ID to delete:")

For i in nameinfo:

If I ['num'] = = del_num:

Nameinfo.remove (I)

While True:

PrintMemu ()

Chose=int (input ("Please enter the number corresponding to the function"))

If (chose==1):

Print ("1: add student information")

Add ()

If (chose==2): print ("2: delete student information") delete () if (chose==3): print ("3: display student information") show () if (chose==4): print ("4: quit the system") break Thank you for reading!
