X = 5
L = list(map(lambda x: 2**X, range(7)))
print (L)
… I’m expecting this to return:
[1, 2, 4, 8, 16, 32, 64]
…instead, it returns:
[32, 32, 32, 32, 32, 32, 32]
What am I doing wrong?
Python is case-sensitive, so
lambda x: 2**Xmeans: take an argument, call it (lowercase)x, ignore it completely, and return 2 to the power of global variable (uppercase)X.
