Question

1. (Python) If the strings r and s are defined by
r = 'ab25wyz9utb725cd'
s = r'\d+'
what is the output?
import re
print(re.findall(r, s))
a. ['ab', 'wyz', 'utb', 'cd']
b. ['ab', '25', 'wyz', '9', 'utb', '725', 'cd']
c. ['25', '9', '725']
d. [25, 9, 725]

2. (Python) If the strings r and s are defined by
r = 'ab25wyz9utb725cd'
s = r'\d+'
what is the output?
import re
print(re.split(r, s))
a. ['ab', 'wyz', 'utb', 'cd']
b. ['ab', '25', 'wyz', '9', 'utb', '725', 'cd']
c. ['25', '9', '725']
d. [25, 9, 725]

Answer 1

(1)

In python, \d means a decimal digit [0-9] eg. 4.6.77, 89,724, ..

in our given question 1 the statement print(re.findall(r, s)) will print all digit which is present in the string r.

After running the above code, image of source code -

So, above we can say the correct output of the given code is an option (c).

(2) In python re.split() split a string that matches a regular expression, and it specifies the regular expression pattern in the first parameter and the target character string in the second parameter.

After running the given code in question 2, the output can be seen as

So form above we can say the correct output is option (c).
