# For loops in Python works like iterator in other language
# Execute a set of statements, once for each item in a list, tuple or set

# Print name in a list of names
names = ["John", "Henry", "Matt", "Rocky"]
for name in names:
  print(name)

# >>>John

#A: Call float(x) with x as either the string "NaN" or "Inf" to create a NaN or Inf value.
nan = float('NaN')
inf = float('Inf')

#Q: How to check NaN of Inf value
#A: math.isnan(x), math.isinf(x)
import math
math.isnan(nan)
>>> True
