# All the Ways to Print 2021/11/06
# the basic string object manipulation... and the print() function

# Ways we build up larger strings
x =  "Sue" # a string!

# CONCATENATION with +
myString = "My name is " + str(x) + ". How do you do?" # all must be strings
# DATA CONVERSION SPECIFIERS or "string modulo"
myString = "My name is %s. How do you do?" % (x) # %i %d, %f
# STRING FORMAT METHOD #........ BEST!
myString = "My name is {}. How do you do?".format(x)
# F STRINGS  #........ also best!
myString = f"My name is {x}. How do you do?"

print(myString)

# THE PRINT() FUNCTION

# print() with no arguments
print()

# print() with one argument
print("Simple, one argument print call.")
print(x)

# print() with multiple arguments
print("Hello", "I'm", "Johnny", "Cash")
print("Hello", "I'm", "Johnny", "Cash", end="\n", sep=" ")
print("Hello", "I'm", "Johnny", "Cash", end=" ")

# print() has optional, hidden arguments

# hidden keyword arguments: end and sep
# default end="\n" for a new line return
# default sep=" "

print("Hello", "I'm", "Johnny", "Cash", sep="--")

myList = ["Agent Scully", "Agent Mulder", "Walter Skinner", "CSM", "Mr. X"] # X-Files characters
for item in myList:
    print(item, end=" ")

print() # get the line return again

# for item in myList: # consider the length vs the index
for i in range(len(myList)):
    if i != len(myList) - 1:
        print(myList[i], end=" ")
    else:
        print(myList[i])

print("String join() method:")
print(" ".join(myList))

print(myString)
print(myString.split())
print(myList)

# SLICES
# a slice is an abbreviated copy of a string, list, even tuple
print(myString[0:7])
revString = myString[::-1]
print(revString)
