2. Language Fundamentals

The first to write a python program "Hello World!"

variable

Only letters, numbers and underscores 
can not begin with a number 
can not be used functionality, such as print 
variable that is used for storing things, to prepare for access

User interaction

Formatted output three kinds of implementations

name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary:")

info ='''
---------- info of '''+ name + ''' ----------
Name:''' + name + '''
Age:''' + age + '''
Job:''' + job + '''
Salary:''' + salary + '''
'''
print(info)

name = input("name:")
age = input("age:")
job = input("job:")
salary = input("salary:")

info ='''
---------- info of %s ----------
Name:%s
Age:%s
Job:%s
Salary:%s
''' % (name,name,age,job,salary)
print(info)

name = input("name:")
age = int(input("age:"))#intger
print(type(age),type(str(age)))
job = input("job:")
salary = input("salary:")

info ='''
---------- info of %s ----------
Name:%s
Age:%d
Job:%s
Salary:%s
''' % (name,name,age,job,salary)
print(info)

name = input("name:")
age = int(input("age:"))#intger
print(type(age),type(str(age)))
job = input("job:")
salary = input("salary:")

info2 = '''
---------- info of {_name} ----------
Name:{_name}
Age:{_age}
Job:{_job}
Salary:{_salary}
''' .format(_name=name,
            _age=age,
            _job=job,
            _salary=salary)
print(info2)

name = input("name:")
age = int(input("age:"))#intger
print(type(age),type(str(age)))
job = input("job:")
salary = input("salary:")
info3 ='''
---------- info of {0}----------
Name:{0}
Age:{1}
Job:{2}
Salary:{3}
'''.format(name,age,job,salary)
print(info3)

if、elif、else的用法

age_of_oldboy = 45

guess_age = int(input("age_of_oldboy:"))

if guess_age == age_of_oldboy:
    print("Yes,you get it.")
elif guess_age < age_of_oldboy:
    print("Think it bigger!")
else:
    print("Think it younger!")

while循环
age_of_oldboy = 45

count = 0
while count <3:
    guess_age = int(input("age_of_oldboy:"))
    if guess_age < age_of_oldboy:
        print("Think bigger!")
    elif guess_age > age_of_oldboy:
        print("Think smaller!")
    else:
        print("Yes,you got it.")
        break
    count +=1
    if count == 3:
        countine_confirm = input("Do you want to keep guessing..?'n'means no ,other touch yes")
        if countine_confirm !="n":
            count =0
else:
    print("You have tried too many times..fuck off")

for循环

age_of_oldboy = 45
for i in range(3):
    guess_age = int(input("age_of_oldboy:"))
    if guess_age < age_of_oldboy:
        print("Think bigger!")
    elif guess_age > age_of_oldboy:
        print("Think smaller!")
    else:
        print("Yes,you got it.")
        break
    else:
    print("You have tried too many times..fuck off")

for i in range(0,10):
    if i <5:
        print("loop",i)
    else:
        continue
        print("hehe")

for i in range(10):
    print('--------',i)
    for j in range(10):
        print(j)
        if j >4:
            break
