Time conversion

Inelegant solution, but it works. It’s quite late now so I’ll think of a more elegant solution another day:

def timeConversion(s):
    # Write your code
    if s[-2:] == "PM":
        s = s.replace("PM", "")
        digits = int(s[0:2])
        if digits != 12:
            digits += 12
            digits = str(digits)
            s = digits + s[2:]
        else:
            pass

    else:
        s = s.replace("AM", "")
        if s[0:2] == "12":
            s = "00" + s[2:]
    return s

Sparse Arrays

Inelegant attempt that didn’t work (it’s like 2 now so I’m going to just sleep and do this again tomorrow)

def matchingStrings(strings, queries):
    # initialise array to track results
    results = []
    # Make results arr as long as queries
    results = [0 for i in range(len(queries))]
    for query in queries:
        for string in strings:
            if query == string:
                results[queries.index(query)] += 1 
            else: 
                pass
    return results
