f.write("this is the 4 line\n")
‘‘‘
# f = open("test.log","r")
# for line in f:
#     if  "3"  in line:
#         print "this is the thrid line"
#     else:
#         print line,
‘‘‘
f = open("test.log","a")
f.write("6\n")
f.write("7\n")
f.close()

输入字符串游戏：

sex = raw_input("input your gender:")
if sex =="girl":
    print("I would like to have a little monkey with monkey king ")
    print("second line")
elif sex == "man":

    for i in range (10):
        if i < 5:
            continue
        if j > 3:
            break
        print(i)

猜幸运数字游戏：

lucky_num = 10
input_num = 0
while lucky_num != input_num:
    input_num = int(input("input your guess lucky_num:"))
    #if input_num == lucky_num:
    #   print("bingo!")
        #break

        print("the real number to smaller")
    elif input_num < lucky_num:
        print("the real number to lager")
print("bingo!")

for 循环：

lucky_num = 50

input_num = 0
for i in range(3):
    print("guess count:",i)
    input_num = input("input your guess lucky_num:")
    if input_num > lucky_num:
        print("the real number to smaller")
    elif input_num < lucky_num:
        print("the real number to lager")
    else:
        print("bingo!")
        break
else:
    print("to many retries")

while 循环：

lucky_num = 50
input_num = 0
guess_count = 0
# while lucky_num != input_num and guess_count < 3:
while  guess_count < 3:
    print("guess count:",guess_count)
    input_num = input("input your guess lucky_num:")
    if input_num > lucky_num:
        print("the real number to smaller")
    elif input_num < lucky_num:
        print("the real number to lager")
       #guess_count = guess_count + 1
    else:
        print("bingo!")
        break
    guess_count += 1
else:
    print("to many retries")
