#NumpyArrayChallenge

✅Create python code to save Numpy Array to txt file and then read the file

N.B. the purpose of this challenge is to learn how to save large numpy array to file and then use for machine learning.

Input ([[1, 6, 3, 4], [2, 3, 4,6],[7,8,9,10], [89, 67, 68, 90]])

Expected output:
1 6 3 4
2 3 4 6
7 8 9 10
89 67 68 90

#Tips

Why NumPy is faster than array list?

✅Size:- Numpy data structures take up less space

✅Performance:- they have a need for speed and are faster than lists

✅Functionality: - SciPy and NumPy have optimized functions such as linear algebra operations built in.

✅Memory:- The main benefits of using NumPy arrays should be smaller memory consumption and better runtime behavior.

Solution by @Abcdefghijklmnopqrstuvwxyz784629
def findLongestWordLength(name):
lis = name.split();
l = len(lis[0])
for i in lis:
if len(i) > l:
l = len(i)
return l;
print(findLongestWordLength("The quick brown fox jumped over the lazy dog"))

#StringReverseChallenge

find the reverse of the given string

eg. "I love Python" then the reverse is "nohtyp evol i"

N.B: don't use any built in reverse function available.

reversed += str[i]
return reversed
print(reverser("i love python"))

✅You can't make the same mistake twice. The second time you make it, it's no longer a mistake, it's a choice.
