Python for迴圈,for i in range(起始值,結束值,間距): #range參數不含結束值

char1 = ” “

for i in range(5) :
#從0開始,間距1,持續5次=> 0 1 2 3 4

#只輸入一個參數,預設從0開始,間距1
    char1 = char1 + str(i) + ” “

print(char1)

#####

char2 = ” “

for j in range(0,4) :
#從0開始,間距1,持續4次=>0 1 2 3

#從0開始,間距1,到4為止,4不算=> 0 1 2 3 
    char2 = char2 + str(j) + ” “

print(char2)

char3 = ” “

for k in range(1,4) :
#從1開始,間距1,持續3次=>1 2 3

#從1開始,間距1,到4為止,4不算
    char3 = char3 + str(k) + ” “

print(char3)

char4 = ” “

for l in range(0,10,2) :
