Chapter 4, Section 4.4 String Methods

 

 1.  Assume that the variable data refers to the string “Python rules!”.

    Use a string method from Table 4.2 to perform the following tasks:

1. Obtain a list of the words in the string.
2. Convert the string to uppercase.
3. Locate the position of the string “rules”.
4. Replace the exclamation point with a question mark.

 

1. Using the value of data from Exercise 1, write the values of the following

    expressions:

1. endswith('i')
2. “ totally “.join(data.split())

Answer 1

data = "Python rules!" # OUTPUT

########################################################3

tokens = data.split(" ") # ['Python','rules!']

print(tokens)

upperCaseData = data.upper() # PYTHON RULES!

print(upperCaseData)

iIndexPos = data.index("rules") # 7

print(iIndexPos)

tweakedData = data.replace("!","?") #Python rules?

print(tweakedData)

print(data.endswith("i")) #False

print(data.endswith("!")) #True

totally = " totally "

outbuff = totally.join(tokens) #Python totally rules!

print(outbuff)
