The print output format in python is: 1. You can use plus sign connection [print("I " "love " "you")]; 2. Comma connection will automatically add spaces between the connection strings [print ("I", "love", "you")]; 3. It can also be connected directly.
The print output format in Python is:
In Python, "" and '' are exactly the same as print( "Hello World!")
# Directly print the string
print('Hello World!')
# For python, single quotes can also represent strings
name = 'Tom'
# Custom variables, weak types, Different from strong types such as C
year = 2018
# Automatically match the int type equivalent to C
print(year)
# Print the content of the variable
print(name) print("Hello " + name)
# Strings can be connected to other types
print("I " + "love " + "you")
# You can use the plus sign to connect
print("I","love","you")
# Comma connection will automatically add spaces between the connection strings
print("I ""love ""you")
# You can also connect directly
print( "Hello {0}".format(name) )
# Formatted output, {0} refers to the 0th element of the output, similarly {1} is the 1st element, {2} is the 2nd...
print( "I am %s, today is %d year"%(name, year) )
# Similar to C Format output, similarly %f is a floating point number...print( f"Today is {year}")
# f string, the element in {} is
for i in range(0,5):
# for loop A kind of loop range [0:5), left closed and right open interval
print(i)
# print() automatically wraps
print(i, end='\n')
# end='', there are two contents in the quotation marks The interval between them, plus end, will not wrap unless end='\n' is specified.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
