Basic python syntax and python syntax

I. Data Types

Python variables do not need to be declared. You can directly assign values to various types of data.

Name = 'zhang san'
Age = 20
Num = 12.5
Print (name, age, num)

Zhang San 20 12.5

II. if judgment

Num = int (input ('num: ') # type conversion

If num = 10: # if condition:
Print ('OK') # subcode indent
Elif num> 10:
Print ('Big ')
Else:
Print ('small ')

3. Loop

Count = 0 while True: # True is the loop condition print (count) # indent count + = 1

For I in range (, 2): # Start from 0, each running cycle, jump 2 numbers, print (I) until 10 # break else: # Run the else code block print ('no') if the loop exists ')
