# ## Exercise: Python for loop
# 1. After flipping a coin 10 times you got this result,
# ```
# result = ["heads","tails","tails","heads","tails","heads","heads","tails","tails","tails"]
# ```
# Using for loop figure out how many times you got heads
print("\nExercise 1\n")

    if item == "heads":
        count += 1

# 3. Your monthly expense list (from Jan to May) looks like this,
# ```
# expense_list = [2340, 2500, 2100, 3100, 2980]
# ```
# Write a program that asks you to enter an expense amount and program
# should tell you in which month that expense occurred. If expense is not
# found then it should print that as well.

# 4. Lets say you are running a 5 km race. Write a program that,
#    1. Upon completing each 1 km asks you "are you tired?"
#    2. If you reply "yes" then it should break and print "you didn't finish the race"
#    3. If you reply "no" then it should continue and ask "are you tired" on every km
#    4. If you finish all 5 km then it should print congratulations message

print("\nExercise 4\n")

# 5. Write a program that prints following shape
# ```
# *
# **
# ***
# ****
# *****
# ```
