Python basic syntax example and python basic syntax example

1. Print the 9-9 multiplication table

# Print only the result for I in range (): for j in range (1, I + 1): print (I * j, end = "") print () # print arithmetic expression for I in range (): for j in range (1, I + 1): print ("{0} * {1 }={ 2 }". format (j, I, I * j), end = "") print () 1*1 = 1 1*2 = 2 2*2 = 4 1*3 = 3 2*3 = 6 3*3 = 9 1*4 = 4 2*4 = 8 3*4 = 12 4*4 = 16 1*5 = 5 2*5 = 10 3*5 = 15 4*5 = 20 5*5 = 25 1*6 = 6 2*6 = 12 3*6 = 18 4*6 = 24 5*6 = 30 6*6 = 36 1*7 = 7 2*7 = 14 3*7 = 21 4*7 = 28 5*7 = 35 6*7 = 42 7*7 = 49 1*8 = 8 2*8 = 16 3*8 = 24 4*8 = 32 5*8 = 40 6*8 = 48 7*8 = 56 8*8 = 64 1*9 = 9 2*9 = 18 3*9 = 27 4*9 = 36 5*9 = 45 6*9 = 54 7*9 = 63 8*9 = 72 9*9 = 81 # transpose the print matrix to I in range): print ("* 10 * (I-1), end =" ") for j in range (I, 10 ): print ("{0} * {1} = {2: <2 }". format (I, j, I * j), end = "") print () 1*1 = 1 1*2 = 2 1*3 = 3 1*4 = 4 1*5 = 5 1*6 = 6 1*7 = 7 1*8 = 8 1*9 = 9 2*2 = 4 2*3 = 6 2*4 = 8 2*5 = 10 2*6 = 12 2*7 = 14 2*8 = 16 2*9 = 18 3*3 = 9 3*4 = 12 3*5 = 15 3*6 = 18 3*7 = 21 3*8 = 24 3*9 = 27 4*4 = 16 4*5 = 20 4*6 = 24 4*7 = 28 4*8 = 32 4*9 = 36 5*5 = 25 5*6 = 30 5*7 = 35 5*8 = 40 5*9 = 45 6*6 = 36 6*7 = 42 6*8 = 48 6*9 = 54 7*7 = 49 7*8 = 56 7*9 = 63 8*8 = 64 8*9 = 72 9*9 = 81

2. Print a diamond (the number of rows is odd)

For I in range (-3, 4): prespace = (-I if I <0 else I) print ("* prespace + '* (7-2 * prespace )) * ************************ # print a piece of deformation Lightning while True: line_max = int (input ("please input a odd number:") if line_max % 2: breakrange_num = (line_max + 1) // 2 for I in range (-range_num + 1, range_num): if I = 0: print ('* line_max) elif I> 0: print (''' * (range_num-1) + "*" * (range_num-i) else: print (''' * (-I) + '* (range_num + I )) * ***************** # deformation to print the hollow diamond for I in range (-4, 5 ): if I =-4 or I = 4: print ('* 9) else: prespace = (-I + 1 if I <0 else I + 1) print ("*" * prespace + ''* (9-2 * prespace) +" * "* prespace) **************************************** ****************

3. Print the Fibonacci series of less than 100

f0, f1 = 0, 1while f1 <= 100:  print(f1, end = " ")  t = f1  f1 = t + f0  f0 = t

Not yet understood:

F0, f1 = 0, 1 while f1 <= 100: print (f1) f0, f1 = f1, f0 + f1 # How does python assign values like this?

4. Calculate the 101st items of the Fibonacci series

f0, f1 = 0, 1for i in range(3,102):  t = f1  f1 = t + f0  f0 = telse:  print(f1)

The above example of the basic python syntax practice is all the content shared by the editor. I hope you can give me a reference and support the help house.
