In the actual development process , You will often encounter many identical or very similar operations , At this time , Code that implements similar operations can be encapsulated as functions , Then call the function where you need it . This can not only realize code reuse , It can also make the code more organized , Increase code reliability . Now let's introduce python Function of the typical case of student management system related content .
example ： Design a student management system , Complete the basic information of students （ Including student ID 、 Name and gender ） The input of 、 Delete and view functions . Copy to pycharm To view the , Very easy to understand .
# Show all student information
def showStuInfo():
print("=" * 20)
print(" The student information is as follows :")
print("=" * 20)
print(" Serial number Student number full name Gender ")
i = 1
# Traverse the list storing student information , Output the details of each student
for tempInfo in stuInfos:
print("%d %s %s %s" % (i, tempInfo['num'],tempInfo['name'], tempInfo['sex']))
i += 1
stuInfos=[] # Used to keep all the information of students
def printMenu(): # Printing function prompt
print("="*20)
print(" Student management system V1.0 ")
print("1. Add student information ")
print("2. Delete student information ")
print("3. Show all student information ")
print("0. Exit the system ")
print("="*20)
# Add a student information
def addStuInfo():
newNum = input(" Please enter the student number of the new student ：") # Prompt and get the student's student number
newName = input(" Please enter the name of the new student ：") # Prompt and get the student's name
newSex = input(" Please enter the gender of the new student （ male / Woman ）：") # Prompt and get the student's gender
newInfo = {
} # Definition dictionary
# assignment
newInfo['num'] = newNum
newInfo['name'] = newName
newInfo['sex'] = newSex
stuInfos.append(newInfo) # Add elements to the list
# Delete a student information
def delStuInfo(student):
del_num = input(" Please enter the student ID of the student you want to delete ：") # Prompt and obtain student ID
for stu in student: # Traverse the list
if stu['num'] == del_num: # Judge whether it is the same as the entered student number
student.remove(stu) # Delete the student information
#main Functions control the flow of the entire program
def main():
while True:
printMenu() # Print function menu
key = input(" Please enter the number corresponding to the function ") # Get user input
if key == '1': # Add student information
addStuInfo()
if key == '2': # Delete student information
delStuInfo(stuInfos)
elif key == '3': # Show student information
showStuInfo()
elif key == '0': # Exit loop
quit_con = input(" Are you sure to quit? ？（Yes or No）：")
if quit_con == 'Yes':
break
main() # call main function
give the result as follows .
