Is there a way to convert number words to Integers?
(17 answers)
Closed 5 years ago.
What is the best way to parse non-digit strings e.g. "twenty two"->22 to integer or double values in python ? Especially what is the best way to detect that region if there are additional words in a sentence.
Thanks

How to replace two things at once in a string?

using .replace to replace more than one character in python [duplicate]

I have a question regarding my code below:
Input: A DNA string Pattern (ex: 'AAAACCCGGT')
Output: The complementary string (ex: 'TTTTGGGCCA')
def Complement(Pattern):
comPattern=Pattern.translate(str.maketrans({'A':'T','T':'A','G':'C','C':'G'}))
return comPattern
I tried using str.replace() method multiple times for above problem, but it did not work. Any idea why?

How do I do a case-insensitive string comparison?
(15 answers)
Closed 3 years ago.
I am trying to compare two string and ignore case- sensitive but i don't want to use .lower() or .upper(). Is there another way of doing this?
example1 = "hello"
example2 = "HeLlo"
if example1.casefold()==example2.casefold():
#do something
This will work without needing upper() or lower(). Might not work for non-ASCII characters.

Split Strings into words with multiple word boundary delimiters
(31 answers)
Closed 3 years ago.
I am trying to split a string using .str.split('$_') but this is not working.
Other combinations like 'W_' or '$' work fine but not '$'. I also tried .str.replace('$') - which also does not work.
Initial string is '$WA:G_COUNTRY'
using
ClearanceUnq['Clearance'].str.split('$_')
results in [$WA:G_COUNTRY]
no split....
whereas
ClearanceUnq['Clearance'].str.split('$')
results in [, WA:G_COUNTRY]
as expected
This is because it is trying to split the string when it finds a $ AND a _ right next to eachother, which does not occur in your first string.

when executing the command in python
str="BANANA"
print(str.count("ANA"))
give answer as 1.
but real answer would be 2. how to solve this
It's true that this might be misleading most tutorial sites say that count returns the number of occurences in the string, it should actually say it returns the nnumber of non-overlapping occurences in the string

Python regex -- extraneous matchings
(5 answers)
Closed 6 years ago.
I searched in all the internet and didnt get a good answer on this thing.
What parentheses in python are stand for? its very wierd..
For example, if i do:
re.split(r'(/s*)', "ho from there")
its will give me a list of separate words with the spaces between that... how does its happening?
This isn't specific to python, but in regex those denote a capture group.
Further information on how these are handled in re.split can be seen here
